Undated (AP) _ Thousands of South Carolinians took refuge inland as Hurricane Bob surged ashore early today, drenching much of the state and southeastern North Carolina with heavy rains before it waned to tropical storm status.

At least 25,000 people were without electricity in the Charleston, S.C., area, where winds up to 77 mph knocked down powerlines, and 7,000 people were in the dark in Myrtle Beach.

Flood watches continued across much of North Carolina as well as across the eastern half of South Carolina as rainfall totals were expected to reach 4 to 8 inches across central and southeastern North Carolina and eastern South Carolina.

Meanwhile, a hurricane watch was posted for the island of Hawaii as Hurricane Ignacio, with sustained winds up to 105 mph and gusts reaching 125 mph, continued to move west at about 12 mph some 500 miles east southeast of Hilo, Hawaii.

Elsewhere across the nation, showers and locally heavy thunderstorms continued from Michigan into northwest Texas and the Texas panhandle, and flooding from heavy rains over the last 24 to 36 hours continues to affect northeast Alabama.

Generally clear skies continued during the early morning from parts of southern New England westward across much of the Ohio Valley, as well as much of the western third of the country.

Temperatures around the nation at 3 a.m. EDT ranged from 42 degrees at Meacham, Ore., to 90 degrees at Phoenix, Ariz., and Las Vegas, Nev.

The National Weather Service forecast for today called for showers and thunderstorms to develop over much of the eastern half of the nation, with thunderstorms most numerous from the upper Great Lakes through the mid- Mississippi Valley, and across the southern Atlantic coast states.

Scattered showers and thundershowers were also forecast over the southern Plains and Arizona, with skies prevailing across New England and much of the Western half of the nation.

Predicted high temperatures were in the 80s and low 90s for most of the nation, the 70s for the northern Great Lakes and northern Minnesota, and between 100 and 110 degrees for much of the desert Southwest and the interior valleys of California.
