Some thunderstorms this afternoon into tonight could be severe (Slight Risk, Level 2 out of 5 for much of NJ and eastern PA) with locally damaging downburst wind gusts the main threat. Small hail is
possible.

Showers and thunderstorms producing very heavy rain this afternoon through Wednesday morning.

Total rainfall amounts will generally range from 1.5 to 2.5 inches with locally higher amounts exceeding 5 inches. Areas of flash flooding are probable mainly for the urbanized portions of New Jersey and eastern Pennsylvania. Hourly rainfall rates with the stronger showers and storms will exceed 2 inches, and where this sets up will result in an increased risk for flash flooding.

A Flood Watch is in effect from 2PM Today through Wednesday morning. This includes all of eastern PA and much of NJ.

Heavy Rain/Flash Flooding potential continues into Thursday.

Tropical Storm Debby will meander across parts of the Southeastern U.S. most of this week. While there is high uncertainty regarding the details for our region, areas of very heavy rain and flooding are
likely late this week.

More information on potential impacts and the timing of potential impacts in our region will be available in the coming days.
