Residents of Southwestern Coos and Northern Grafton County are being warned of possible flash floods due to heavy rain.
The National Weather Service issued a flash-flood warning about 7:30 saying in the following two hours an additional one to two inches of rain was expected and streams were rising rapidly.
It said areas of concern include “but are not limited to Franconia Notch State Park, Littleton, Franconia, Crawford Notch and Bethlehem.”
The warning was expected to end about 10:45 p.m.
The National Weather Service defines a warning as more severe than a watch. A warning means "conditions are occurring or are expected to occur."
Dispatchers with the New Hampshire State Police Troop F and Grafton County said as of 8:30 pm no problems had been reported.
Traditionally rivers causing concern would be the Gale, Ammonoosuc and Pemigewasset.
