Erin has undergone rapid intensification. It went from a tropical storm on Friday morning to a major category 4 hurricane north of the Leeward Islands on Saturday morning.

Forecast data show Hurricane Erin will be a very large storm too. We measured the diameter of the storm to be over 650 miles according to this data.

Track guidance is now very consistent in keeping Erin over open water.

Tropical Storm Watches are now up for some of the most northern Leeward Islands. There could also be concerns along the East Coast of the U.S. dealing with rip currents.
