A severe thunderstorm warning has been issued for New York City, southern Westchester County and Rockland County in New York state and Hudson, eastern Union, southeastern Bergen and Essex counties in New Jersey. The alert also covers northwestern Nassau County on Long Island.
A flash-flood warning is also in effect for NYC until 8 p.m.
A cold front sweeping across the region is promising to unleash damaging wind gusts, torrential downpours and frequent lightning. In addition, there is the threat for some large hail and even a tornado.
Severe Thunderstorm and Flash Flood Watches have been posted through Monday evening as the storms cross through the region. Any of these storms are capable of producing 60 to 70 mph gusts. Heavy rainfall rates associated with the torrential downpours will cause flooding on area roadways and some small creeks and rivers to rise in a short period.
The dangerous weather should start to taper off after 8pm or so. Despite this, there could still be a linger shower or so through the night.
A severe thunderstorm watch is in effect for all five boroughs, Long Island, and these areas in New Jersey and Connecticut. It will remain in place through 8 p.m.
The brunt of the storm is forecast to begin before the evening rush and last through the commute, promising a messy ride home for many. Commuters — by car, train, bus or subway — are urged to give themselves more travel time and go slowly.
A flash flood watch has been issued from 12 p.m. through late Monday for the following counties:
- Staten Island
- New Haven
