Storms move past NYC, hit Long Island as they weaken

The strongest storms made their way through New York City by 10:30 p.m. or so, and were working east through Long Island.
Those storms weakened as they continued to head east onto the island. Severe weather is not anticipated for the rest of the night, but heavy downpours and lightning will still be common.

PSE&G: ‘Prepared' for incoming storm, potential power issues
By NBC New York Staff
How much rain can we expect from Monday's storms?
By Storm Team 4
Heavy downpours will be likely, but how much accumulation is the NYC area likely to see?
Overall, the storms will deliver a substantial amount of rain throughout the tri-state, especially along the I-95 corridor, where the heaviest pockets of rain will set up for a couple of hours.
In those spots, one to two inches of rain are likely, with isolated higher amounts. The rest of the area can expect anywhere from a half inch to an inch of rain, while those further north and west in the Hudson Valley will see comparatively lower totals, likely less than a half inch.
That amount of rain could lead to flooding, especially in low-lying areas.
Tornado risk not zero for tonight so make sure to stay ‘weather aware'
By Storm Team 4
While a tornado occurring in the tri-state tonight is not likely, the risk is not zero. Storm Team 4 describes it as a tertiary threat with the chance existing of an isolated tornado or two, mainly west of the Hudson River. The National Weather Service's Storm Prediction Center puts the probability of a tornado around 2%, but the fact that it is not zero, is notable and worthy of our attention.
"The primary threat remains damaging wind gusts, with large hail also possible, and an isolated tornado cannot be totally ruled out," the National Weather Service says.
Here's information from the NYC emergency management office on how to prepare for a tornado.
Timing of storms: Will commutes be impacted?
By Storm Team 4
When will Monday's storms start hitting the New York City area, and how will the weather impact evening commutes? That depends on where you are.
Those in NYC, Northern Jersey, the Hudson Valley and Connecticut could be dealing with thunderstorms or heavy rain as they drive home, and roads conditions could be heavily impacted. Those hitting the road should drive carefully.
Those along the Jersey Shore and on Long Island will have an easier time getting home, as the lines of storms won't have arrived there yet.
Monday evening's severe weather threats
By Storm Team 4
Here's a breakdown of what weather threats we could be seeing this evening. Highest chance is for high winds, but hail and flooding from downpours also present a moderate threat.
