Bahamas preparing for hit from Dorian

The sounds of hammers banging into plywood and cash registers dinging are echoing across the Bahamas as the archipelago that lies southeast of Florida rushes to prepare for Hurricane Dorian .

The Category 2 storm is expected to strengthen in its approach to the northwest Bahamas on Saturday and then move over or near that region Sunday.

Dorian was located 480 miles (770 kilometers) east of the northwest Bahamas at 11 a.m. EDT on Friday. It had maximum sustained winds of 110 mph (175 kph) and was moving northwest at 10 mph (17 kph).

A hurricane watch was in effect for northwestern Bahamas, where long lines formed at gas stations and grocery stores Friday. Supplies like canned food and bottled water were quickly disappearing in Grand Bahama Island.
