  northern and eastern Maine. For the season ahead, no strong signal 

  for temperatures to be anomalously above or below normal. 

* Precipitation: For April, CPC is forecasting for likely above 

  normal precipitation. There is no strong signal for anomalously 

  above or below normal precipitation for the next three months 

  overall. 

* ENSO: Per CPC, transition to ENSO-neutral conditions in the

  coming month or so. 55% chance for ENSO-neutral May-July. Then, 

  El Nino has a 62% chance of developing in June-August.
