Wind Advisory
Statement as of 10:39 AM EST on November 11, 2009
... Wind Advisory in effect until 5 am EST Thursday...
The National Weather Service in Wilmington has issued a Wind Advisory... which is in effect until 5 am EST Thursday.
Low pressure is developing off the South Carolina coast this morning and is expected to strengthen as it moves slowly north tonight and Thursday. Strong high pressure will remain centered across New England. The pressure gradient between these two features will increase the northeast to north winds across the advisory area. Sustained winds of 15 to 25 mph will gust up to 35 mph through tonight. Given the ground is fully saturated... winds of this magnitude may bring down a few trees which are still fully leaved. Isolated power outages are possible.
Precautionary/preparedness actions...
A Wind Advisory means that winds of 35 mph are expected. Winds this strong can make driving difficult... especially for high profile vehicles. Use extra caution especially on bridges and overpasses.
