Winter Weather Advisory  WINTER WEATHER ADVISORY   Winter Weather Advisory
COASTAL ROCKINGHAM COUNTY

Areas Affected:
Coastal Rockingham
Effective: Sun, 1/22 10:39pm Updated: Mon, 1/23 2:56am Urgency: Expected
Expires: Mon, 1/23 10:00pm Severity: Minor Certainty: Likely

 
Details:
...WIDESPREAD MODERATE TO HEAVY SNOWFALL THROUGH MONDAY...
.Low pressure will cross New England tonight before exiting through
the Gulf of Maine on Monday. This will bring another round of
snowfall to the region. Moderate to heavy snowfall rates are
expected overnight tonight into Monday morning, with travel impacts
expected for the morning commute. There is a growing signal that a
band of moderate to heavy snow will develop in the afternoon into
the early evening hours, bringing difficult travel for the evening
commute. Snow may be wet and sticky across the south, which may
increase power outage risk. Power outage risk increases further as
winds turn gusty out of the northwest behind the storm system on
Monday afternoon into Monday night.
...WINTER WEATHER ADVISORY REMAINS IN EFFECT UNTIL 10 PM EST
MONDAY...
* WHAT...Snow. Total snow and sleet accumulations between 3 and 5
inches. Winds gusting as high as 35 mph Monday evening.
* WHERE...Coastal Rockingham County.
* WHEN...Until 10 PM EST Monday.
* IMPACTS...An area of low pressure will bring a period of snowfall
to the region. Travel will be impacted due to snowfall
accumulations on roads. The potential exists for snowbands that
will bring periods of locally heavy snowfall Monday afternoon,
which will lead to rapid snow accumulations and extremely
dangerous travel conditions. The hazardous conditions could impact
the Monday evening commute.

Information:
Slow down and use caution while traveling. The latest road
conditions can be obtained by going to newengland511.org
