A powerful coastal storm with strong winds and heavy rain will impact the east coast beginning later this weekend, potentially resulting in tree damage, power outages, and flooding. A wind event is possible Sunday or Monday according to the National Weather Service. This storm system will also receive an injection of moisture and energy from Tropical Depression eighteen in the western Caribbean.
The National Weather Service in Boston has stated that this is an unusual and strong, potentially dangerous storm system for late October. In general, this east coast storm will be quick moving as it rushes northward this weekend into Monday. The storm timing is as follows:
Saturday: Tropical moisture from TD 18 will fuel heavy rain in south Florida before being pulled into the developing east coast storm. Rain will begin to push into the interior Northeast and Appalachians.
Sunday: Heavy rain and increasing winds will begin to affect locations from the Outer Banks of North Carolina into the Northeast by Sunday morning.
Sunday night: Peak impacts from the storm begin to ramp up in the Northeast during this time, including the potential for damaging winds and heavy rainfall.
Monday: Potentially damaging winds and heavy rain may continue over parts of New England and upstate New York, at least during the first half of the day.
We expect to see to see wind gusts up to 60 mph in some areas, and they could be higher depending on the intensity and track of the storm. The potential for higher end wind gusts will be greatest along the immediate coast and in higher terrain locations, particularly in New England. Three main impacts from this storm are as follow:
Tree damage and power outages will be possible, through areas of the greatest concern are still uncertain.
The strong winds will likely cause delays at major airports.
Onshore southeast winds ahead of the storm could result in some coastal flooding, along with high surf.
Heavy rainfall can be expected along the coast and well into parts of Pennsylvania, New York and Boston areas. Rainfall can top off at 5 to 6 inches in some locations, as well as flash flooding and mixed precipitation in the higher elevations.
