Written by NH1 Weather on .
GRAY, Maine — A flash flood watch has been issued for parts of New Hampshire and Maine beginning at noon on Wednesday.
The National Weather Service said a stalled frontal boundary and a very moist air mass will boost the development of showers and thunderstorms this afternoon, which will then continue into tonight.
Torrential downpours will likely occur in the areas under watch, and there is a potential for flash flooding, with a good chance of urban and small stream flooding.
The following New Hampshire counties are in the flood watch area: Belknap, Cheshire, Eastern Hillsborough, Interior Rockingham, Merrimack, Northern Carroll, Southern Carroll, Southern Grafton, Strafford, Sullivan, and Western and Central Hillsborough.
The following counties in Maine are also in the flood watch area: Androscoggin, Central Somerset, Interior Cumberland, Interior Waldo, Interior York, Kennebec, Northern Franklin, Southern Franklin, Southern Oxford, and Southern Somerset.
The National Weather Service estimated that 2 to 4 inches of rain could be possible by early Thursday morning, in addition to accumulation from heavy rain on Tuesday.
The flash flood watch will remain in effect until Thursday morning.
