I’ve been watching this awhile, as have many others, and now it looks like we might have some real trouble. Matthew looks to be strengthening – see the satellite loop below.
Besides winds, huge amounts of rain and storm surge will accompany this storm.
Hurricane expert Dr. Ryan Maue says of the animation above:
Pressure at 934 mb in Hurricane Matthew. Improved satellite representation, expansion of cold cloud-tops suggests slightly stronger
He also opines on this series of forecast maps that show Matthew grazing the east coast of Florida:
Margin of error is small as Hurricane Matthew likely will parallel Florida east coast — hopefully well offshore. GFS 18z is too close.
