Watches and warnings currently in effect

Hurricane Warning for Bermuda

Meaning of the different watches and warnings

A Hurricane Warning means that hurricane conditions are expected somewhere within the warning area. A warning is typically issued 36 hours before the anticipated first occurrence of tropical-storm-force winds, conditions that make outside preparations difficult or dangerous. Preparations to protect life and property should be rushed to completion.

Hazards affecting land

Wind. Hurricane conditions are expected over Bermuda by Wednesday evening, with tropical storm conditions likely by Wednesday afternoon.

Rainfall. Across Bermuda, 2 to 4 inches (50 to 100 mm) of rainfall are expected from Wednesday into Thursday, which could lead to flash flooding.

Storm surge. In Bermuda, a dangerous storm surge is expected to produce coastal flooding in areas of onshore winds. The surge will be accompanied by large and damaging waves.

Surf. Swells generated by Hurricane Imelda and Hurricane Humberto are affecting the Bahamas and are currently spreading to much of the U.S. east coast. These swells are likely to cause life-threatening surf and rip current conditions.
