Hurricane Danielle now a Category 4 Storm

Hurricane Danielle became a Category 4 storm early Friday out over the Atlantic as it headed in Bermuda's direction and threatened to bring dangerous rip currents to the U.S. East Coast.

Danielle's maximum sustained winds increased to near 135 mph with some additional strengthening possible.

Danielle was located early Friday about 545 miles southeast of Bermuda and moving north-northwest near 12 mph. The hurricane is forecast to pass well east of Bermuda on Saturday night. But large waves and dangerous surf conditions were expected in Bermuda over the next few days, the National Hurricane Center in Miami said.

Swells from Danielle would also begin arriving on the East Coast of the U.S. on Saturday and were likely to cause dangerous rip currents through the weekend.

Add to the mix Tropical Storm Earl.  Earl was moving west with maximum sustained winds near 45 mph. Forecasters said Earl could become a hurricane by Saturday night.

And in the Pacific, Hurricane Frank had weakened slightly off Mexico's coast. Further weakening was expected over the next couple days as the hurricane moved over cooler waters.
