Tropical Storm Colin pushing into the coastal Carolinasa

The National Hurricane Center said Colin was centered about 5 miles west of Myrtle Beach, South Carolina, with winds reaching 40 mph.

Colin's heaviest rain and high winds were off the coast of the Carolinas and at sea on Saturday morning.  Still, locally heavy rain -- up to 4 inches -- could fall over parts of coastal South and North Carolina by Sunday morning, the center said.

A Tropical Storm Warning was in effect for the northern third of the coast of South Carolina as of Saturday morning, as well as for much of the coast of North Carolina.  The warning means tropical storm conditions - including sustained winds of at least 39 mph - were possible within the next 36 hours.

Colin is forecast to move toward the coast of North Carolina late Saturday through Sunday before entering the open Atlantic Ocean and turning away from the US by Sunday night.

The day's greatest risk for severe weather -- a "slight" risk, or Level 2 of 5 -- appears over eastern Montana and the Dakota, as well as extending from northern Virginia to New England, the Hurricane Prediction Center said.

This includes Washington, DC;  Baltimore, Philadelphia;  New York City;  and Boston.  The center said that there could be destructive winds and hail.

It is one of the rare storms to cross the Pacific from the Atlantic without losing tropical storm force, thus retaining its name.  Forecasters said Bonnie was likely to become a hurricane off Mexico's south coast this week, but was unlikely to hit land directly.

Many Nicaraguas still remember the Hurricane Zone, a powerful 1988 hurricane that wreaked havoc on the coast and caused nearly 150 deaths in the country.

"We're waiting for the storm to hit, hopefully it won't destroy our area," said Bluefields resident Ricardo Gomez, who was 8 years old when the zone hit, before Bonnie arrived.
