1113 PM EST Wed Nov 9 2022
.SYNOPSIS...
High pressure will slowly slide south of the region overnight
into Friday while a cold front becomes stationary across
northern Maine Thursday, and slowly lifts north to the Saint
John Valley as a warm front by Friday. Low pressure will
approach from the southwest Friday night and cross the area
Saturday with a cold front followed by weak high pressure for
Sunday. An upper trough will move across the region from the
west Sunday night into Monday as a weak surface low moves across
the Maritimes from the open Atlantic.....
......SHORT TERM /THURSDAY NIGHT THROUGH SATURDAY/...
Summary: Significantly above normal temperatures are expected
Thursday night through Saturday, and particularly Friday night
into Saturday. Heavy rain will develop from the remnants of
Tropical Storm Nicole Friday night into Saturday. Localized
flooding is possible depending on the track of Nicole’s remnant
low, which remains uncertain.
Thursday Night: Northern Maine will be just south of a warm
front associated with an occluding low over the western Great
Lakes Thursday night. Isolated showers associated with the warm
front may clip northern portions of the Saint John Valley, but
otherwise dry conditions are expected with partly to mostly
cloudy skies keeping low temperatures in the 40s and near or in
some cases above the average high temperatures for this time of
the year.
Friday/Veterans Day: The area will remain south of the warm
front and north of moisture from the remnants of Tropical Storm
Nicole. A break in cloud cover is possible between these two
features, with the most likely area with a period of sunnier
skies across central portions of the forecast area. 850mb
temperatures will be well above freezing, resulting in high
temperatures climbing into the 60s.
Friday night to Saturday: Remnants of Tropical Storm Nicole will
lift northward across the Mid-Atlantic and into New England
Friday night, merging with the mean upper level trough across
the Great Lakes. Highly anomalous precipitable water values and
northward water vapor transport will result in heavy rain. The
system will ingest a considerable amount of dry air from the
western Gulf of Mexico, resulting in a dry slot wrapping around
its eastern periphery. The northward extent of the dry slot in
Maine will depend on the low track, which remains uncertain.
Trends over the past 24 hours have shown a track across the far
northwestern portion of the forecast area. The heaviest rainfall
amounts and greatest chance of over two inches appears to be
along and just northwest of the low track, which for now appears
to be across Northern Aroostook County and into the North Woods.
Along the initial leading edge of precipitation and ahead of the
dry slot, isolated thunderstorms are possible given at least a
few hundred joules of elevated CAPE. Patchy advection fog is
also possible Downeast and over the waters late Friday night
into Saturday morning as dew points rise into the low to mid
60s. Record high temperatures are possible again on Saturday.
Depending on the width of the dry slot, a few spots across
Interior Downeast may reach into the 70s, but most areas will
see highs in the 60s.
&&
.LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/...
Saturday night to Sunday: Low pressure will depart into the
Maritimes with cooler air and lingering isolated showers, mainly
across the north and west. Temperatures will be much cooler but
unlike behind the last system, winds will not be strong this
time as an inverted trough hangs back across central Quebec and
keeps the pressure gradient from becoming too steep. Highs
Sunday will be slightly above normal with mid to upper 40s
across the north and low to mid 50s Downeast.
Sunday night: A quick moving shortwave trough will become
negatively tilted, resulting in a surface low forming across
the Gulf of Maine and quickly moving northeast as it deepens.
There is considerable uncertainty on the timing of this
transition, but a quick accumulation of snow across northern
Maine Sunday night cannot be ruled out given at least marginal
ensemble support.
Monday to Tuesday night: Canadian high pressure will build
across the area. Seasonably cool temperatures, dry conditions,
and partly to mostly clear skies are forecast.
Wednesday: The next upper level trough will approach the area on
Wednesday into Wednesday night. Ensembles indicate a variety of
possible low tracks, but this will be the next appreciable
threat of precipitation and snow after the Sunday night system.....

DISCUSSION AND OUTLOOK
----------------------
At 1000 PM EST (0300 UTC), the center of Hurricane Nicole was
located near latitude 27.0 North, longitude 78.9 West. Nicole is
moving toward the west-northwest near 13 mph (20 km/h). A turn
toward the northwest is expected on Thursday, followed by a turn
toward the north and north-northeast on Friday. On the forecast
track, the center of Nicole will move onshore the east coast of
Florida within the hurricane warning area late tonight or early
Thursday. Nicole's center is then expected to move across central
and northern Florida into southern Georgia Thursday and Thursday
night, and into the Carolinas Friday.
Maximum sustained winds are near 75 mph (120 km/h) with higher
gusts. Little change in strength is expected until Nicole makes
landfall along the Florida east coast. Nicole is expected to
weaken while moving across Florida and the southeastern United
States Thursday through Friday, and it is likely to become a
post-tropical cyclone by Friday afternoon.
Hurricane-force winds extend outward up to 25 miles (35 km) from the
center and tropical-storm-force winds extend outward up to 485 miles
(780 km), especially to the north of the center. A WeatherFlow
station at Juno Beach Pier recently reported a wind gust of 55 mph
(89 km/h), and a C-MAN station at Settlement Point on Grand Bahama
Island recently reported a wind gust of 55 mph (89 km/h).
The estimated minimum central pressure is 980 mb (28.94 inches).
HAZARDS AFFECTING LAND
----------------------
Key messages for Nicole can be found in the Tropical Cyclone
Discussion under AWIPS header MIATCDAT2, WMO header WTNT42 KNHC,
and on the web at www.hurricanes.gov/text/MIATCDAT2.shtml.
WIND: Hurricane and tropical storm conditions will continue across
portions of the northwestern Bahamas through tonight. Tropical
storm conditions will continue along portions of the east coast of
Florida, Georgia, and South Carolina in the warning areas into
Thursday. Hurricane conditions are expected within the hurricane
warning area in Florida tonight or Thursday morning. Hurricane
conditions are possible within the hurricane watch area tonight.
Tropical storm conditions are expected within the warning area along
the west coast of Florida tonight and Thursday.
STORM SURGE: The combination of a dangerous storm surge and the
tide will cause normally dry areas near the coast to be flooded by
rising waters moving inland from the shoreline. The water could
reach the following heights above ground somewhere in the indicated
areas if the peak surge occurs at the time of high tide...
* North Palm Beach Florida to Altamaha Sound Georgia including the
St. Johns River to the Fuller Warren Bridge...3 to 5 ft
* Anclote River to Ochlockonee River...3 to 5 ft
* Altamaha Sound Georgia to the South Santee River South
Carolina...2 to 4 ft
* St. Johns River south of the Fuller Warren Bridge to Georgetown
Florida...2 to 4 ft
* Hallandale Beach to North Palm Beach...2 to 4 ft
* Ochlockonee River to Indian Pass...2 to 4 ft
* Englewood to Anclote River including Tampa Bay...1 to 3 ft
* North of Ocean Reef to Hallandale Beach including Biscayne Bay...1
to 2 ft
* South Santee River to Surf City North Carolina...1 to 2 ft
Storm surge could raise water levels by as much as 4 to 6 feet above
normal tide levels along the immediate coast of the northwestern
Bahamas in areas of onshore winds.
The deepest water will occur along the immediate coast near and to
the north of the landfall location, where the surge will be
accompanied by large and destructive waves. Surge-related flooding
depends on the relative timing of the surge and the tidal cycle, and
can vary greatly over short distances. For information specific to
your area, please see products issued by your local National Weather
Service forecast office.
RAINFALL: Nicole is expected to produce the following rainfall
amounts through Saturday:
Northwest Bahamas into the eastern, central and northern portions of
the Florida Peninsula: 3 to 5 inches with local maxima of 8 inches.
Southeast into the southern and central Appalachians, western
Mid-Atlantic, and eastern portions of Tennessee, Kentucky, and Ohio:
2 to 4 inches with local maxima of 6 inches along the Blue Ridge.
Northern Mid-Atlantic into New England: 1 to 4 inches.
Flash and urban flooding will be possible, along with renewed river
rises on the St. Johns River, across the Florida Peninsula today
into Thursday. Heavy rainfall from this system will spread
northward across portions of the Southeast, eastern Ohio Valley,
Mid-Atlantic, and New England Thursday through Saturday, where
limited flooding impacts will be possible.
TORNADOES: A few tornadoes will be possible overnight into early
Thursday morning across east-central to northeast Florida. The
tornado threat will increase and gradually expand north through the
day into southeast Georgia and southern South Carolina. Some
tornado risk should continue Thursday night into early Friday across
eastern South Carolina and southeast North Carolina. Tornadoes
will again be possible during the day Friday centered on central to
eastern North Carolina into southeast Virginia.
SURF: Large swells generated by Nicole will affect the northwestern
Bahamas, the east coast of Florida, and much of the southeastern
United States coast during the next few days. These swells are
likely to cause life-threatening surf and rip current conditions.
Please consult products from your local weather office.

Hurricane Nicole Discussion Number 12
NWS National Hurricane Center Miami FL AL172022
1000 PM EST Wed Nov 09 2022
The hurricane has large intense bands extending quite far from the
center, but does not have a distinct Central Dense Overcast.
Flight-level wind observations from Hurricane Hunter aircraft
indicate that the maximum winds are near 65 kt. Dvorak satellite
classifications gave a slightly lower intensity, probably because
the system does not have a classic tropical cyclone appearance at
this time. Nicole has a large eye over 50 nmi in diameter, and a
very large extent of tropical-storm-force winds over its northern
semicircle.
Nicole has made its expected turn toward a west-northwestward
heading and the motion estimate is now 285/11 kt. The system
should turn toward the northwest and north during the next day or
so while moving along the western side of a mid-level anticyclone,
moving over the Florida peninsula and northern Florida. In 36 to
48 hours, Nicole should accelerate north-northeastward to the east
of a longwave mid-tropospheric trough. The official track forecast
is about the same as the previous one and remains close to the
multi-model consensus prediction.
The hurricane has little time to strengthen further before making
landfall in Florida. Weakening will occur while Nicole moves over
Florida, and even though the center may briefly emerge over the
extreme northeastern Gulf of Mexico, this is not likely to result in
any significant re-intensification. The system should weaken to a
depression and become a post-tropical cyclone over the southeastern
United States. Nicole should merge with another extratropical low
over the eastern United States after 48 hours.
Key Messages:
1. Hurricane and tropical storm conditions and a dangerous storm
surge are expected to continue over portions of the northwestern
Bahamas tonight, where a Hurricane Warning remains in effect.
2. Hurricane conditions are expected across portions of the coast
of southeast and east-central Florida tonight, where a Hurricane
Warning is in effect. Tropical storm conditions will continue along
the east coast of Florida, Georgia, and South Carolina within the
warning areas into Thursday. Tropical storm conditions are expected
to begin along the west coast of Florida tonight and Thursday.
3. A dangerous storm surge is expected along much of the east coast
of Florida, portions of coastal Georgia, and the Florida Big Bend
along the Gulf coast. The storm surge will be accompanied by large
and damaging waves along the Atlantic coast. Residents in the
warning area should listen to advice given by local officials.
4. Do not focus on the exact track of Nicole since it is a large
storm with hazards extending well to the north of the center,
outside of the forecast cone. These hazards will affect much of the
Florida peninsula and portions of the southeast United States.
5. Nicole will produce heavy rainfall tonight into Thursday across
the Florida Peninsula. Flash and urban flooding will be possible
across portions of the Florida Peninsula along with renewed river
flooding on the St. Johns River. Isolated flash, urban, and small
stream flooding will also be possible on Friday in the Southeast
through the southern and central Appalachians, including the Blue
Ridge Mountains, and extending northward through west-central
Pennsylvania into western New York by Friday night into Saturday.

Tropical cyclone information statement for:
New Brunswick
Nova Scotia
Prince Edward Island
Québec - south:
Îles-de-la-Madeleine
The next information statement will be issued by 2:00 p.m. AST Thursday.
For Tropical Storm Nicole.
Tropical Storm Nicole (near hurricane-strength at the time of this bulletin) is heading toward Florida and likely will landfall as a category-one hurricane early tomorrow. Nicole will then turn northward travelling over land (Georgia, The Carolinas) while merging with a cold front and becoming post tropical. The combined weather system is expected to track through New England early Saturday and into the Maritimes Saturday evening.
Since the storm is expected to transition to 'post-tropical' well to our south, it will essentially be an autumn type storm while impacting Eastern Canada. Heavy rain will spread well north of the low's track as far north and west as Lake Erie and Lake Ontario then into southern Quebec. Rain and wind is expected over the Maritime provinces with very mild, tropical temperatures and gusty winds south of the track and cold northeasterly winds north of it. This frontal low will likely track somewhere through New Brunswick. Parts of central and eastern Quebec and eventually Newfoundlland could even see some snow, so this will clearly be a non-tropical storm and this bulletin is in effect for the 'tropical side' of the system.
Rainfall could be in the 50 to 100 mm range along and north of the track. We do not anticipate very strong winds - but there will be two windy parts of the low both north and south - perhaps gusting in the neighborhood of 70 km/h in some areas. Details will appear in local forecasts from the regional weather offices starting tomorrow night. Elevated water levels and wave activity is likely in the northern Gulf of St Lawrence affecting northeastern New Brunswick and the Gaspe region that could cause some minor flooding so we will monitor and provide details later.
The CHC will continue to track this system with once-a-day updates but we will not be issuing a specific track forecast.
