A Nor���Easter occurred during Sunday and Monday, April 15th and 16th.  It brought heavy rain and high winds that caused widespread and significant river, stream, and urban flooding of low lying and poor drainage areas.  High winds downed many trees and power lines across Southeast Connecticut.  The combination of high winds, heavy rain, and high water tables produced widespread moderate tidal flooding across portions of the Long Island Sound Shorelines through Thursday, April 19th.  Significant river flooding lasted through Monday, April 23rd.
Storm Total Rainfall amounts ranged from 1.76 inches at New London Airport in Groton to 7.83 inches in New Canaan.
Fairfield County rainfall ranged from 3.49 inches at Bridgeport to 7.83 inches at New Canaan.
New Haven County rainfall ranged from 3.32 at Oxford Airport in Waterbury to 4.50 inches at Hamden.
Middlesex County rainfall at Middletown was 5.25 inches.
New London County rainfall at New London Airport was 1.76 inches.
Flooding from Rainfall:
The heaviest rain fell across southwest and southcentral Connecticut, where many small rivers, streams, and brooks rose over their banks within 12 hours of the heavy rainfall during Sunday, April 15th.
River Flood Observations include:
Long stem larger rivers, such as the Housatonic and the Connecticut Rivers rose over their banks the following day, on Monday, April 16th.  The Yantic River rose above its' flood stage of 9.0 feet at 3:45 am on April 16th.  It crested at 10.42 feet at 10:42 am, then fell below flood stage at 9:45 pm on April 16th.
Urban Flood Observations include:
Trained spotters reported sewage drains overflowing in Greenwich, street flooding in Trumbull, Old Greenwich, and Hamden; and flooding along I-95 in Fairfield and New Haven Counties.
High Wind Observations include:
The highest winds occurred across southeast Connecticut during Saturday night from April 15th to the 16th.
East winds increased during the day, Sunday as the low approached.  Wind speeds gusted from 35 to 55 mph.  As the low moved toward Long Island, another period of high winds occurred during Sunday night with peak wind speeds from 45 to 55 mph.  The National Weather Service (NWS) Automated Surfacing Observing System (ASOS) measured a peak wind gust of 53 mph from the Southeast at Meriden Markham Airport in Meriden on April 16th.  The NWS ASOS measured a peak wind gust of 52 mph from the Southeast at New London Airport on April 15th.  Based on the receipt of many downed trees and power lines in New London County Sunday night, instantaneous peak wind gusts of 60 to 70 mph were estimated.
Tidal Flooding:
Coastal flooding occurred along the Long Island Sound shores of Connecticut around the times of high tide starting Sunday evening, and lasting through Thursday, April 19th.  The highest surges of 3 to 4 feet occurred across the Southeast shores of CT Sunday evening.  Because of the new moon on April 17th, the highest water levels (and highest tidal departures) occurred during Tuesday, April 17th.  Water slowly receded during the remainder of the week, when mainly minor tidal flooding occurred during Wednesday and Thursday.
