3. PUBLIC WEATHER IMPACTS AND WARNINGS SUMMARY
THE REMNANTS OF BERYL ARE NOT FORECAST TO AFFECT THE MARITIMES UNTIL
FRIDAY AND NEWFOUNDLAND ON THE WEEKEND.
4. MARINE WEATHER IMPACTS AND WARNINGS SUMMARY
BERYL IS FORECAST TO ENTER CANADIAN WATERS ON FRIDAY AND COULD BRING
SOUTHERLY GALE FORCE WINDS TO SOUTHWESTERN WATERS.
5. TECHNICAL DISCUSSION
A. ANALYSIS
TROPICAL STORM BERYL GAINED A BIT OF STRENGTH THIS MORNING WHILE EAST
OF CAPE HATTERAS. THE STORM IS OVER 28-DEGREE SSTS. AIRCRAFT RECON
AROUND 12Z REPORTED MAX FLIGHT LEVEL WINDS OF 52 KNOTS WHICH SUPPORTS
SURFACE WINDS NEAR 40 KTS.
B. PROGNOSTIC
THIS STORM WILL LIKELY GAIN MORE STRENGTH OVER THE NEXT 24 HOURS AS
IT REMAINS OVER 26C+ SSTS. THEREAFTER..IT WILL SPEND ABOUT ANOTHER
12 HOURS OVER 24-26C SSTS. AFTER THAT WE EXPECT BERYL TO BE MOVING
OVER WATERS UNDER 20C AS IT MOVES EAST OF CAPE COD EARLY FRIDAY.
LITTLE OR NO BAROCLINIC ENHANCEMENT IS LIKELY AS THE STORM MOVES OVER
THE COOL WATERS..AT LEAST INITIALLY.
THE MAIN QUESTION IS HOW STRONG WILL BERYL BECOME BEFORE MOVING OVER
THE COOLER WATER. NUMERICAL GUIDANCE SUGGESTS UP TO 50 KTS. 60 KTS
WOULD NOT BE OUT OF THE QUESTION GIVEN THE WARM WATERS. THE MAXIMUM
INTENSITY ACHIEVED WILL NATURALLY HAVE A BEARING ON THE FORECAST AS
IT MOVES TOWARD THE MARITIMES.
OUR CURRENT FORECAST TRACK LIES IN THE MIDDLE OF VARIOUS NUMERICAL
MODEL TRACKS. A FULL ASSESSMENT OF ALL 12Z MODELS IS NOT POSSIBLE
UNTIL AFTER 18Z TODAY..HOWEVER..THE MOST LIKELY SCENARIO HAS BERYL
MOVING NEAR OR JUST EAST OF CAPE COD WITH CLOUD AND PRECIPITATION
MERGING WITH A DEVELOPING COLD FRONT OVER NEW ENGLAND ON FRIDAY.
THE MERGING OF STORM AND FRONT MAY LEAD TO SOME HEAVY RAINFALL OVER
PARTS OF THE MARITIME PROVINCES AND EVENTUALLY NEWFOUNDLAND. IT IS
TOO EARLY TO ANTICIPATE AMOUNTS OR WHETHER WE WILL EXPERIENCE MUCH
WIND FROM IT..BUT WE WILL HAVE BETTER IDEA BY EARLY THURSDAY.
ANALYSIS OF THE NOGAPS CYCLONE PHASE SPACE FROM OVERNIGHT SUGGESTS
THAT ET MAY BE COMPLETED WHEN BERYL ENTERS CANADIAN TERRITORY ON
FRIDAY..IN WHICH CASE WEATHER CONDITIONS MAY BEHAVE MORE LIKE A
FRONTAL WEATHER SYSTEM WITH ABUNDANT MOISTURE AND GUSTY WINDS.
