A flash flood watch has been issued for much of the Tri-State Area on Monday. It takes effect at 2 p.m. and lasts until at least midnight. It's a First Alert Weather Day, as we track downpours, thunderstorms and the enhanced risk of flash flooding across portions of New Jersey.

Excessive rainfall could lead to flash flooding as showers and thunderstorms move across the Lehigh Valley and eastern Pennsylvania on Monday afternoon and night.

We will have a heightened threat for heavy rain producing t'storms this afternoon and evening. The flood risk will be highest between 2 and 8 pm today. The southeastern part of Central PA has seen so much rain recently that it's not going to take much for flash flooding to occur. This is where the flood risk will be more significant.
