Storms erupting across the interior Northeast will pack a punch in some communities with the risk of torrential downpours, high winds and hail into Tuesday night.
"While a heavy, gusty thunderstorm can occur just about anywhere in the Northeast, the greatest concentration of strong storms will be over Pennsylvania and New York state into Tuesday night," according to AccuWeather Lead Storm Warning Meteorologist Eddie Walker.
Where downpours repeat, there will be an elevated risk of flash, urban and small stream flooding.
Winds can be strong enough in some of the storms to down trees, damage power lines and cause minor property damage.
Some of the strongest storms can produce hail large enough to damage crops, vehicles and homes.
A small number of the strongest storms may produce a brief tornado.
Seek shelter indoors as storms approach. Lightning is the most dangerous aspect of thunderstorms.
Motorists should anticipate delays, especially along the Pennsylvania Turnpike, Interstate 80, I-81 and I-90. Motorists may need reduce their speed due to sudden low visibility and excess water on the roads.
Airline passengers with flights at secondary airports should anticipate delays. These delays may then expand to the major airports as storms approach part of the I-95 corridor toward evening.
Additional storms are likely to erupt on Wednesday.
The unsettled weather pattern with frequent rounds of showers and thunderstorms is likely to continue well into June.
