[ARCHIVED] STRONG STORM SYSTEM FORECAST TO IMPACT CONNECTICUT SUNDAY AND MONDAY

DEMIS

Good Afternoon

At 1:30 PM light to moderate rain was falling across most of the state.  Winds are from the southeast at 15 - 20 MPH, gusting to 25 MPH at times.  Eversource and UI are reporting a total of 432 customers without power at this time.   

At 11:00 AM Tropical Storm Philippe was located at 27.8 N 77.5 W or approximately 180 miles east of Vero Beach, Florida.  T.S. Philippe had maximum sustained winds of 50 MPH and was moving to the east northeast at 31 MPH.  The National Hurricane Center (NHC) is forecasting that T.S. Philippe will become post-tropical in the next few hours as much of the storm is absorbed into the developing northeaster along the east coast.   

A low pressure system currently located well north of T.S. Philippe near the coast of North Carolina is forecast to rapidly intensify during the next 6 hours.  This storm is forecast to move north up the coast and reach our area this evening.  The following forecast is based on a blend of the GFS, NAM and HRRR computer models:

This Afternoon: Light to moderate rain is expected for the next 4 - 5 hours.  Moderate to heavy rainfall is expected to move into the state from the south between 6:00 - 7:00 PM.  Winds are forecast to gust to 40 MPH by 6:00 PM.   

This Evening and Overnight: Rain heavy at times with strong southeast winds gusting to 50 - 60 MPH at the coast and 45 - 55 MPH inland.  The strongest winds and heaviest rainfall are expected between 7:00 PM and 1:00 AM.  Rainfall rates close to 1" per hour are possible at times especially in Western CT.  The strong winds may cause a moderate number of power outages and the heavy rainfall is expected to cause minor to moderate urban flooding and minor river and stream flooding.  Total rainfall is forecast to range from 2" - 3" in eastern CT up to 3" - 5" in western CT.  The rain and wind are expected to taper off to showers and lighter winds after 1:00 AM.    

Monday: Showers during the morning with clearing during the afternoon.  Strong winds shifting to the west and continuing with gusts between 35 - 45 MPH during the day.  The strong winds will likely cause additional power outages.  The overall impact of this event is still expected to be moderate.  

The Department of Emergency Services and Public Protection Division of Emergency Management and Homeland Security will continue to closely monitor this storm and will send out the next update at 7:00 PM this evening.
