This storm system has begun weakening, but maintains an unusually low barometric pressure (29.59 inches of mercury / 1002 mb) centered over the Long Island Sound. Over the past hour, MRMS 1-hour radar estimates show rainfall rates peaking between 0.5-1.0"/hr.

Additional rainfall totals of 1-2 inches with localized amounts up to 4" are possible from the southern New England coast to as far north as Downeast Maine through Thursday night. Additional flash flooding, along with elevated creeks, streams, and rivers, are expected through Thursday, particularly in areas where soils are most sensitive.

Flood Watches and Flood Warnings are active across the Northeast. For a detailed graphical depiction of the latest watches, warnings and advisories, please see www.weather.gov At 1000 AM EDT...At 1000 AM EDT...NWS radar and surface observations depict widespread heavy rain showers and embedded thunderstorms overspreading eastern New York, Long Island, and southern New England. An unusually strong surface low pressure system (29.47 inches of mercury / 998 mb) centered over southwestern Connecticut is tracking slowly northwestward. A surge of rich tropical moisture streaming ahead of the low is interacting with the higher terrain of the eastern Catskills and Berkshires, producing heavy rainfall rates of 1 to 2 inches per hour. Saturated ground from rain over the past 24 to 30 hours is compounding the flash flood risk, particularly in urban areas and low-lying spots. ...Selected preliminary Storm Total Rainfall in inches from 700 AM EDT Tue Jul 28 through 1000 AM EDT Thu Jul 29... ...CONNECTICUT...

Broad areas of moderate to heavy rain will continue across portions of the New York Capital Region, Hudson Valley, and New England through this afternoon into tonight. General additional rainfall amounts of 2 to 4 inches are expected, with localized storm totals reaching 6 to 10 inches where heavy rain bands repeatedly track over the same locations. Flash flooding remains likely in urban, low-lying, and poor drainage areas. Rainfall intensity will gradually ease to lighter, scattered showers and drizzle Thursday into Friday as moisture weakens and the storm moves away. The next Storm Summary will be issued by the Weather Prediction Center at 1100 PM EDT. Please refer to your local National Weather Service office for additional information on this event.
