July 13, 2010 Storm Updates

An area of heavy storms moved through the area in the last 1-2 hours, which dumped heavy rain up to 1-2 inches for the immediate NYC area. These storms were only the start of what is likely to be a wet day for the area, with more rain likely tonight and tomorrow. Rainfall totals are expected to end up between 1 and 3 inches for parts of the area, with locally higher amounts.

The observations for today’s storms are going to be posted below, including short term forecasts.


5:00 PM: The heavy rain coverage has ended for now. There is still heavy rain affecting Long Island and Connecticut, which should continue to do so for at least the next hour or two. Other than an isolated storm or two, northern NJ and SE NY are dry.

Looking at the regional radar, however, there is an area of heavy rain in West Virginia and SW PA, moving ENE. This should mainly stay to our south, however it could bring some heavy rain, especially to the southern and eastern parts of the area. More details on this area of rain will come with an update tonight.

4:24 PM: Heavy rain is currently moving through the rest of southern Connecticut, bringing rainfall amounts between 1/4 and 1/2 inch. The heaviest rain is located in western CT, which moved through SW CT and Brooklyn earlier, bringing 1-2 inches of rain. This cell is moving NNE.

Another round of heavy rain just moved into eastern Long Island, bringing very heavy rainfall. Additional 1-2 inches of rain are expected with this round.

3:22 PM: Looking at the latest radar, there are several areas of concern. The first is with the main band of rain currently moving through eastern Long Island, with lighter rain approaching south central CT, including Bridgeport and New Haven. This band is producing very heavy rainfall for eastern Long Island, with up to an inch possible in just 1/2 hour. A total of 1-2 inches of rain is likely there from this band.

Lighter rain is currently falling in southwestern and south central CT, with amounts up to 1/2 to 1 inch expected, though heavier rain may move into southeastern CT later this afternoon with the band in Long Island.

Light to moderate rain is also moving into NYC and NE NJ, with generally light rainfall amounts. Another area of storms is nearly stationary in central Morris county, NJ, which is slowly shifting north towards eastern Sussex and western Passaic counties.
