As Category-4 Hurricane Matthew batters Haiti and the rest of the Caribbean with powerful 145-mile-per-hour winds and rain today, we're getting a more complete picture of the threat the storm poses to the United States.
A hurricane watch is in effect for the East Coast of Florida. Current models have Matthew striking Florida as a "major" hurricane late Thursday or Friday with winds over 110 mph, and then maintaining hurricane strength as it moves up the East Coast.
Here's the map of the projected path:

As a general rule of thumb, hurricane projections after three days into the future are hazy, so we don't know yet how exactly Matthew's path through the US will look. But Floridians should prepare for a major storm, and the rest of the East Coast should keep a close eye on updates.
