MIAMI, Florida (CNN) -- Hurricane Ike struck the Turks and Caicos Islands as a Category 4 storm late Saturday night with winds near 135 mph, according to the National Hurricane Center in Miami, Florida.

The outer bands of the storm brought fierce, palm-bending winds and a scattering of rain to the British crown colony that had already been pummeled this week for four days by Tropical Storm Hanna.

"People are losing roofs by the second," said Audley Astwood, a reporter at a radio station in Grand Turk said. "Close to 50 percent of the homes on Grand Turk have been destroyed or lost roofs."

In fact, Astwood said his own home lost its roof and his family was huddled in a bathroom.

Power was out over the whole island of Grand Turk, he said.
