PA Weather: Hazardous Weather Outlook Issued Ahead Of Stormy Tuesday

The abundant sunshine that graced us for the past several days is on its way out, and Eastern Pennsylvania is about to be hit with some of the roughest weather we've had in a month. The National Weather Service has issued a Hazardous Weather Outlook for the Philadelphia region due to heavy rainfall that is likely Tuesday morning and afternoon.

The Hazardous Weather Outlook is in place in Bucks, Chester, Delaware, Montgomery and Philadelphia counties, as well as in the Lehigh Valley.

The storms may cause localized flooding of roadways and areas of poor drainage, forecasters predict.

Scattered strong thunderstorms are expected, and pockets of damaging wind are possible Tuesday, especially during the afternoon, according to the National Weather Service.

The change in the weather pattern will bring the return of rain and cool air to the northeastern United States this week, while elevating the risk for travel disruptions, according to AccuWeather.

“Across much of this region, it has been dry recently, which should mean that the ground can absorb most of the rainfall,” AccuWeather Lead Long-Range Meteorologist Paul Pastelok said in a news release. The pace of the storm should limit the period of heaviest rain and the flood threat to a localized level.

“[However], watch for street flooding,” Pastelok said.
