National Weather Service Issues Flash Flood Warnings

The National Weather Service has issued a flash flood watch for Merrimack, Hillsborough, and Rockingham counties through 2 a.m. on Friday, Oct. 17.

The alert was issued at around 2:30 p.m. 

Rain will be heavy at times through this evening causing problems in urban and poor drainage areas, leading to the potential – and dangerous – flash floods.

The heaviest rain is expected to hit later this afternoon and continue into the early evening in the southern to western part of the state while slowing moving east and north.

As much as 2.5 inches will fall by the end of the storm, according to the report.

The NWS is also warning about the southern and eastern part of the White Mountains where as much as four inches of rain is expected to fall during a short period of time.

If you see floods in the road, do not drive into the water.

“Flood waters are usually deeper than they appear,” the warning stated. “Just one foot of flowing water is powerful enough to sweep vehicles off the road. When encountering flooded roadways, make the smart choice: Turn around, don’t drown.”

The rain is expected to taper off by midnight.
