Hurricane Irma is still a powerful Category 5 hurricane with maximum sustained winds of 185 mph.

The latest computer models have shifted Irma towards the east coast of Florida on Sunday but all of Southwest Florida remains in the 5-day forecast cone. A great deal of uncertainty still exists about Irma's ultimate path.

As of 5 a.m., Irma is located about 35 miles east/southeast of St. Martin and is moving west/northwest at 16 mph. The minimum central pressure is 914 mb.

On the forecast track, the extremely dangerous core of Irma will move over portions of the northern Leeward Islands this morning, move near or over portions of the northern Virgin Islands later today, and pass near or just north of Puerto Rico this afternoon or tonight.

Some fluctuations in intensity are likely during the next day or two, but Irma is forecast to remain a powerful category 4 or 5 hurricane during the next couple of days.

Hurricane-force winds extend outward up to 50 miles from the center and tropical-storm-force winds extend outward up to 175 miles. St. Martin recently reported a wind gust of 61 mph.
