THE HEAVY RAINFALL HAS DEPARTED THE STATE…SEVERAL TOWNS HAVE REPORTED URBAN FLOODING AND A FEW TOWNS HAVE REPORTED SIGNIFICANT DAMAGE TO ROADS, RAIL ROADS AMD BRIDGES…

All of the Flood Advisories and Flash Flood warnings have expired.  Several Flood Warnings for rivers that are above flood stage remain in effect. 


Total rainfall ranged from 1 – 3 inches across central Connecticut, 3” – 5” in southeastern CT and up to 8” – 11” in the NW Hills.  The map to the right shows total rainfall as of 7:00 AM.  Some additional rainfall occurred in Southeastern CT after 7:00 AM. 


Urban flooding was reported in East Lyme, New London and several other towns in southeastern CT.  Significant infrastructure damage was reported in Norfolk and Cornwall.  Preliminary analysis indicates that the rainfall in the NW Hills exceeded the 10-year storm in a few towns for a 3-hour duration of very heavy rainfall.  Many older culverts are designed for the 10-year storm and some of these culverts failed when the 10-year storm was exceeded. 

The Housatonic River at Gaylordsville is cresting at this time at 10.9 feet which is just over the moderate flood stage of 10.0 feet. 


The Connecticut River at Hartford is forecast to crest at 23.2 feet at 1:00 PM on Wednesday, just below the moderate flood stage of 24.0 feet. 

Towns should continue to report any significant flood damage to their DEMHS Regional Coordinators as time permits.  This will be the final update on this event from DESPP / DEMHS.
