2:40 a.m.

Hurricane Irma is moving to the northeast of the Dominican Republic after blacking out much of Puerto Rico and raking the U.S. territory with wind and rain.

The U.S. National Hurricane Center says the Category 5 storm's maximum sustained winds are near 180 mph (290 kph). The hurricane center says some fluctuations in strength are likely during the next day or two but Irma is expected to remain a powerful Category 4 or 5 hurricane.

As of 2 a.m. EDT, the storm was about 140 miles (225 kilometers) northwest of San Juan, Puerto Rico, and is moving west-northwest near 16 mph (26 kph).

2 a.m.

As Hurricane Irma bears down on Florida, an Associated Press analysis shows a steep drop in flood insurance across the state, including the areas most endangered by what could be a devastating storm surge.

According to Federal Emergency Management Agency data, in just five years, the state's total number of federal flood insurance policies has fallen by 15 percent.

Florida's property owners still buy far more federal flood insurance than any other state - 1.7 million policies, covering about $42 billion in assets - but most residents in hazard zones are badly exposed. Fully 59 percent of the owners of properties in flood hazard zones don't have this insurance, despite requirements to have the coverage as a condition of their federally backed mortgage loans.

FEMA, which is ultimately responsible for enforcing flood insurance requirements, didn't respond to an email seeking comment from its Washington office.
