Harvey Rapidly Intensifying: Major Hurricane Possible

http://www.nhc.noaa.gov/graphics_at4.shtml?cone#contents
Forecast 16

















#12,716


What a difference 6 hours can make, particularly when a tropical system moves into the right conditions. This morning, the forecast was for a strong CAT 1 storm reaching the Texas coast on Saturday morning, now it looks like either a strong CAT 2 or CAT3 storm.

Should Harvey have CAT 3 strength at landfall, it would be the first major hurricane to hit the continental United States since Wilma in October of 2005, and would end the longest drought in major hurricane hits in recorded history.  

New details from the 10am CDT forecast follow.  All those in the path of this storm need to take it very seriously.

Storm surge estimates, particularly for the coastal back bays, have increased to over 9 feet.


With tropical storm force winds arriving along the coastline as early as 8am tomorrow morning, all residents in the path of the storm should be making preparations for Harvey's arrival - and any decisions to evacuate low lying or unsafe areas - while weather conditions still permit.


Residents should closely monitor the National Hurricane Center in Miami, Florida and their local Emergency Operations Center for advisories and updates. These are the real experts, and the only ones you should rely on to track and forecast the storm.
