WIND: Hurricane conditions are expected on Bermuda Saturday, with tropical storm conditions likely beginning later this afternoon. STORM SURGE: A dangerous storm surge is expected to produce significant coastal flooding on Bermuda in areas of onshore winds. Near the coast, the surge will be accompanied by large and destructive waves. RAINFALL: Ernesto is expected to produce total rain accumulations of 6 to 12 inches in Bermuda with isolated maximum amounts up to 15 inches.

Swells are expected to spread up the east coast of the United States later today and continue into the weekend, and could reach portions of Atlantic Canada by late Saturday. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office, and stay out of the water if advised by lifeguards.
