Flood Watch

01/12/2018 8:39 PM through 01/13/2018 4:45 AM

Update to NWS-IDP-PROD-2624858-2462275

Flood Watch issued January 12 at 8:39PM EST expiring January 13 at 12:00PM EST by NWS Gray ME

Alert

Rain will continue tonight. One and a half to three inches of
rainfall is expected across the region with the highest amounts
across the high terrain across central New Hampshire and adjacent
areas of western Maine as well as the Midcoast region of Maine.
At the same time, very warm temperatures will continue for the
next several hours in the mountains and through morning to the
south, leading to considerable snowmelt and runoff.

The combination of these two factors will lead to river rises and
potential for ice jams. Any ice jams could produce rapid rises in
river levels. Urban and poor drainage flooding is also possible
as well, especially in areas where remaining snow banks pool
water along streets.

Colder and drier air will enter the region from north to south
late tonight and Saturday, gradually easing the threat for
flooding.
The Flood Watch continues for

* Portions of Maine and New Hampshire, including the following
areas, in Maine, Androscoggin, Coastal Cumberland, Coastal
Waldo, Coastal York, Interior Cumberland, Interior Waldo,
Interior York, Kennebec, Knox, Lincoln, Sagadahoc, Southern
Franklin, Southern Oxford, and Southern Somerset. In New
Hampshire, Belknap, Cheshire, Coastal Rockingham, Eastern
Hillsborough, Interior Rockingham, Merrimack, Northern
Carroll, Northern Grafton, Southern Carroll, Southern Grafton,
Strafford, Sullivan, and Western And Central Hillsborough.

* Through Saturday morning

* A combination of heavy rainfall, snow melt and potential ice
jams may cause flooding on rivers and streams as well as in
urban and poor drainage areas. Rainfall amounts 1.5 to 3
inches are expected. The heaviest rainfall is expected to
occur through tonight.

* Rivers and streams could see locally fast and significant
rises in vicinity of any ice jams. Urban and poor drainage
flooding may occur.
