329 AM EDT Thu Jul 23 2026

...FLASH FLOOD WARNING IS CANCELLED FOR NORTHEASTERN DAVIDSON, 
FORSYTH, GUILFORD AND NORTHERN RANDOLPH COUNTIES...

Periods of rain ON Wednesday evening and this morning have dropped 
between 2 to 4 inches of rain across much of Guilford and 
southeastern Forsyth counties. A few locations have received close 
to 5 inches. This has resulted in many streams and creeks rising to 
near bankfull but the prolonged duration of the rain has precluded 
flash flooding.

The widespread heavy rain has relaxed and rainfall rates have 
decreased significantly. Thus the risk of flash flooding has 
decreased.

Additional showers and thunderstorms are expected this morning and 
given that the ground is saturated and creeks and streams are 
already high, it will not take much in the way of additional heavy 
rain to produce flash flooding. Please continue to monitor weather 
information for updates and possible warnings.

A Flood Watch remains in effect until 1200 AM EDT Friday for central 
North Carolina.
