Update to Sandy/Nor'easter
Folks:
The
National Hurricane
Center continues to issue advisories and forecasts on
Hurricane Sandy (see attached).
If
you've been following...this track is definitely a shift
WEST and stronger, maintaining Hurricane status offshore of North
Carolina before turning "Post Tropical" (aka - Powerful Nor'easter)
before making landfall between Cape Cod and Jersey shore on
Tuesday.
The exact path will determine the type and magnitude of the impacts
for the North Country (Vermont and Northern NY).
A track closer to NJ/NYC would mean a greater wind threat for the
North Country.
A track across CT/RI/Cape Cod would mean a Rain and Wind
threat.
Wind Threat:
At this moment, this may be the bigger threat.
Confidence is Moderate.
Strong east to northeast winds could exceed 50 mph
or MORE, especially exposed hills/ridges and in
downslope locations such as the western slopes of Vermont's Green
Mountains and portions of Northern NY.. Scattered to widespread
power outages may be likely, especially if these winds occur with
saturated soils, thus fallen trees.
Rainfall:
At this moment...heaviest rainfall threat MAY be NY vs.
Vermont.
Again...so much can change that
both states need to be prepared for potential
heavy rainfall of 2 to 5 inches and possibly localized more. Downed
leaves will plug storm drains, thus urban, road flooding will be
very likely. Minor to potentially Major flooding of
streams...particularly mountain streams and rivers are
possible.
Any flood threat will likely be different than Irene in that this
will be a longer duration event 24-30+ hours vs. 12 hours. Max
rainfall rates may be .25 inch or more per hour with this system
vs. 0.50 to 1 inch per hour with Irene. The end result will mean it
will take longer to flood and it may be more focused on stream and
river flooding with only localized FLASH FLOODING.
Confidence of a flood threat is Low to Moderate at this point, but
could change significantly depending on the track.
Timing:
Rain threat as early as Sunday in NY...possibly holding off til
late Monday in VT.
Winds increasing during Monday into Tuesday.
AGAIN...there remains much uncertainty being 5 days out. However,
be prepared to plan for the worse and hope for the best, including
closely monitoring future weather forecasts and other
information.
Here's what we're hearing in Vermont; its not good!
Guys any updates on Hurricane heading for East Coast? Hearing ...
