FLOOD WARNINGS REMAIN IN EFFECT ACROSS PARTS OF THE STATE…FINAL BAND OF HEAVY RAINFALL MOVING THRU NORTHERN AND EASTERN CONNECTICUT AT THIS TIME…

At 7:45 am radar showed moderate to heavy rain falling across northern and most of eastern Connecticut.  Flood Advisories are in effect for Eastern New Haven County until 8:30 AM.  A Flash Flood Warning is in effect for southern Middlesex and New London Counties until 10:45 AM.  A Flood Warning is in effect for minor flooding on the Housatonic River at the Stevenson Dam.  A Flood Warning is also in effect for most of Litchfield County until 9:30 AM.  Minor urban flooding with ponding on roadways is also occurring across much of northern and eastern CT. 


A large area of moderate to heavy rain (see map to the right) over the state is moving to the north and towns in Northern and Eastern CT can expect another  2 – 3 hours of moderate to heavy rain.  Some additional narrow bands of heavy rain may develop during the midday with the daytime heating.  However, these bands should be isolated to just a few towns.


Total rainfall thus far from this storm has ranged from around 1” – 2” across central and eastern CT up to 8” - 10”+ in the NW hills especially from Cornwall to   Norfolk and Goshen.  Significant flood damage has been reported in Norfolk.


Much more widespread heavy rainfall is expected in northern New England today.  The runoff from this rainfall is expected to cause minor flooding on the Housatonic and Connecticut rivers over the next 3 – 4 days.  This minor flooding and the associated faster than normal water currents can be a hazard to boating and swimming. 


Local Emergency Management Directors should report any significant flood damage to their DEMHS Regional Coordinators as time permits. 

DESPP / DEMHS will continue to monitor any isolated additional bands of heavy rainfall that may develop during the mid-day.
