It won't take much rain to spur moderate flooding in some neighborhoods because the ground is so saturated following Ida's deadly wrath last week. That's why we're issuing a First Alert that will last through 3 a.m. Thursday.
It's important to note that the flooding will be nothing like what we experienced last week. Still, it's important to be prepared.
A Flash Flood Watch will remain in effect until 4 a.m. Thursday for Philadelphia and its surrounding Pennsylvania counties as well as the Lehigh Valley and Mercer County in New Jersey.
A Flash Flood Warning is also in effect for Lehigh and Northampton counties until 1:45 a.m.
The thunderstorms could pack damaging winds and flash flooding as well. Given the very saturated soils from recent heavy rain, additional brief heavy rainfall of one to two inches may quickly lead to flooding in flood-prone and low-lying areas due to rapid runoff.
An isolated tornado is also possible during the overnight hours in the Lehigh Valley, Berks County, northwest suburbs and Philadelphia. There will also be a slight chance of a tornado along the I-95 corridor.
Since the line will mostly be moving through during nighttime hours, instability will be limited by the time the system tries to advance into Delaware and New Jersey around 3 a.m. so the severe risk in those areas is much more limited. Counties in eastern Pennsylvania will be hit the hardest during the storm.
