Hurricane Dorian’s top sustained winds have decreased slightly to 165 mph, but the Category 5 storm is still pounding the northern Bahamas. Forecasters say Dorian is crawling along Grand Bahama island at 1 mph in what they say is likely to be a daylong assault. There’s little information from the affected islands, though officials expect that many residents have been left homeless. The east-central coast of Florida may experience a “brief tornado” Monday afternoon or evening.
