Storms could bring heavy rain and flash flooding from Virginia to Connecticut
New Jersey Lt. Gov. Tahesha Way declared a state of emergency for the state in advance of the storms.
'Flash flooding is possible with fast-moving thunderstorms, especially with already saturated ground. Please take all necessary precautions,' Way wrote in a post on X.
Forecasters said the strongest storms were expected later Thursday afternoon and night. The National Weather Service said heavy to excessive rainfall and potentially severe thunderstorms were expected along the Washington-Philadelphia-New York City corridor. Some areas in the southern part of the corridor could see rainfall rates of 2 inches (5 centimeters) per hour, the service said.
The weather service issued flash flood warnings early Thursday afternoon for parts of Berks, Lancaster and York counties in Pennsylvania and parts of Baltimore and Hartford counties in northern Maryland, meaning heavy rain was falling. The service said flooding was possible in small creeks and streams and urban areas, along with highways, streets, underpasses and poor-drainage and low-lying areas.
Flood watches and severe thunderstorm watches were in effect in the region until late Thursday and Friday, with 4 to 6 inches (10 to 15 centimeters) of rain possible in some areas. The weather service posted a severe thunderstorm warning for an area of eastern Pennsylvania between Allentown and Reading, saying 60 mph (97 kph) wind gusts and penny-size hail were possible.
Pennsylvania Gov. Josh Shapiro posted on social media that state emergency management officials were preparing potential response and recovery efforts.
New York City officials warned that heavy rain could flood some streets, parts of the subway and basements. They urged people living in basements to move to higher floors and issued an advisory asking New Yorkers to avoid travel from Thursday afternoon through Friday afternoon.

Massive California wildfire keeps growing — becomes state's largest blaze of the year
Rising temperatures on Wednesday posed new challenges for firefighters who have made incremental progress against a massive wildfire in central California that has injured four people as it has become the biggest blaze in the state so far this year. More than 870 remote homes and other structures at the northern edge of Los Padres National Forest are threatened by the Gifford Fire, which grew only slightly overnight after burning out of control for days. The fire has scorched at least 131 square miles (339 square kilometers) of Santa Barbara and San Luis Obispo counties, with just 9% containment. 3 A massive wildfire has injured four people across central California, as this latest blaze is the biggest one to hit the state this year. AP It surpassed the 126-square mile (326-square-kilometer) Madre Fire, which erupted last month in southeastern San Luis Obispo County, as the state's largest fire of 2025. Crews working in steep, inaccessible terrain will be dealing with temperatures in the mid-90s (35 Celsius) on Wednesday and above 100 (38 Celsius) on Thursday, said Capt. Scott Safechuck with the Santa Barbara County Fire Department. 'We have hot weather, and we have low relative humidity,' Safechuck said Wednesday. 'So we expect extreme fire behavior.' Luckily, winds are expected to remain relatively calm, he said. Wildfire risk will be elevated through the weekend across much of inland California as the heat wave intensifies. 3 The wildfires covered at least 131 square miles across the areas of Santa Barbara and San Luis Obispo.
