On the heels of Hurricane Harvey, now estimated to be the second-costliest storm in U.S. history, attention is turning to the next threat, Hurricane Irma.
Irma, which weakened slightly overnight — now down to Category 2 strength with sustained winds of 110 mph — is currently marching westward across the Atlantic Ocean. Irma’s center of circulation is still more than 2,000 miles away from U.S. coast, but signs continue for future concern.
As highlighted Friday, this storm will definitely be one to watch over the next several days — particularly along the East Coast — despite the high uncertainty in impacts at this juncture.
Current status
Although it has dropped to Category 2 strength, Irma continues to look quite healthy on satellite images, as of this morning.
Irma initially underwent rapid intensification on Thursday — it is already the longest-duration storm at hurricane strength of the 2017 Atlantic season — and these kinds of fluctuations should be expected in an intense storm that far east.
