Wind Advisory in effect until 1 PM EST Monday...
The National Weather Service in Mount Holly has issued a Wind
Advisory... which is in effect until 1 PM EST Monday.
The double barrel low pressure systems around the area will merge
into one near eastern Maine overnight and continue to intensify on
its way through the Canadian Maritimes on Monday.
West winds will continue to increase tonight and probably reach
their peak during the first half of the day on Monday. Sustained
west winds will increase to 20 to 30 mph with peak gusts reaching
around 45 mph.
These wind speeds should knock down some weak trees, tree limbs
and wires. The trees are going to be under pressure from separate
forces. From the Interstate 95 corridor and northwestward there is
still ice on some trees. This will make it easier for them to be
snapped. Farther to the southeast, precipitation totals so far
this month have averaged twice the normal December amount already.
The supersaturated soil will make it easier for shallow rooted
trees to be knocked down.
In addition to the wind, this air mass will be the coldest one of
the season so far. Wind chill factors come Monday morning will
average around zero with readings well below zero over the higher
terrain. Please dress appropriately if you have to spend much time
outdoors.
Be prepared for the likelihood of scattered power outages. Also
if possible do not park vehicles under trees that are encased in
ice or are shallow rooted such as Willows. A Wind Advisory means
that wind gusts of around 45 mph are expected. Winds this strong
can make driving difficult... especially for high profile vehicles
especially on north to south overpasses. Use extra caution. Winds
will diminish Monday afternoon as the intense low pressure system
slowly moves farther away.
