Two hurricane hunter aircraft were flying through Hurricane Isaias tonight. The measurements were about what we expected.
What You Need To Know
- Hurricane Warning for part of Florida east coast
Isaias is a category 1 hurricane headed for the southeastern coast of Florida.
It will gradually turn to the north but will likely make landfall or at least scrape along the eastern side of Florida late Saturday night through Sunday.
A general idea of the strongest winds and heaviest rain will be from about West Palm Beach northward through Cape Canaveral.
This is not a large hurricane in size, so the impacts will be concentrated close to where the center goes. That means there will be wide-varying conditions from east to west across the state with some hurricane winds right along the immediate east coast, but yet just a breeze on the Gulf side of Florida.
From Orlando south and eastward there will be heavy rain squalls with strong wind gusts starting late Saturday night going into Sunday.
From Polk County westward into Tampa Bay the weather will be mainly quiet Saturday, with increasing scattered thunderstorms Sunday. The winds around Tampa Bay will be breezy on Sunday, mainly in the 20s and 30s mph range.
Polk County might see some winds into the 40s to low 50s, but the strongest winds will definitely be from Osceola County eastward to the coast.
Isaias will slow down once it moves into Florida, then turn north and exit toward the Atlantic on Sunday night to Monday. It will be a weaker storm at that time and then head for the Carolinas.
It’s too early to know exactly where it will likely make a second landfall, but it will probably be somewhere between Myrtle Beach and Wilmington, NC. The intensity will likely be much lower at that point due to its land interaction and wind shear.
Isaias will pick up speed and race up the east coast of the U.S. from the Carolinas all the way to the Northeast between Monday and Tuesday.
