SAN JUAN, Puerto Rico (AP) — The outer bands of Hurricane Humberto lashed Bermuda on Tuesday as it approached the tiny British territory, with newly formed Hurricane Imelda following closely behind.

A hurricane warning was in effect for the island in the north Atlantic as forecasters advised of dangerous seas, strong winds and heavy rain.

Humberto was located about 295 miles west-northwest of Bermuda. The Category 1 storm had maximum sustained winds of 80 mph and was moving north at 17 mph, according to the National Hurricane Center in Miami.

Humberto was a Category 4 storm on Monday, but was quickly losing strength and was forecast to dissipate by today.

Imelda was expected to pass near or over the island late today as a Category 2 hurricane, according to the Bermuda Weather Service.
