North Atlantic Ocean: Hurricane Larry tracking northwestward in North Atlantic Ocean early Sept. 8 /update 3

Event

Hurricane Larry is tracking northwestward in the North Atlantic Ocean early Sept. 8. As of 05:00 AST, the system's center of circulation was approximately 970 km (605 miles) southeast of Bermuda. Forecast models indicate that Larry, currently a Category 3 hurricane, will weaken into a Category 2 hurricane while continuing to track northwestward through Sept. 8.

The system is subsequently forecast to turn north-northwestward and then northward as it makes a close approach to Bermuda, likely passing to the east of the territory, the afternoon of Sept. 9. Larry is likely to gradually weaken as it tracks generally northward then northeastward across the North Atlantic Ocean through Sept 10 and make landfall as a Category 1 hurricane over far southeastern Newfoundland and Labrador Province, Canada late Sept. 10. After landfall, the system is forecast to weaken as it tracks northeastward, transitioning into a post-tropical cyclone with tropical storm strength winds through early Sept. 12. Larry is likely to weaken further as it tracks north-northeast, alongside the southeastern coast of Greenland through early Sept. 13. Some uncertainty remains in the track and intensity forecast, and significant changes could occur in the coming days.

Government Advisories
As of 05:00 Sept. 8, the Bermuda Weather Service has issued a Tropical Storm Watch for Bermuda. Officials may announce further weather advisories in the coming days as Larry approaches Bermuda.

Hazardous Conditions
Tropical storm conditions are likely to begin to impact Bermuda by late Sept. 8. Swells generated by Larry are forecast to impact the Leeward Islands, portions of the Greater Antilles, and the Bahamas, through at least Sept. 8, and Bermuda through at least Sept. 11. Significant swells will likely impact parts of the US East Coast and Atlantic Canada Sept. 8-11.

Sustained heavy rainfall could trigger flooding in low-lying communities in Bermuda in the coming days. In addition to the heavy rain, flooding, and storm surge, the storm could produce damaging wind gusts, resulting in power outages due to uprooted trees and toppled utility lines.

Advice

Activate contingency plans in areas forecast to be impacted by the storm. Use extreme caution in low-lying areas and near streams, creeks, and other waterways due to the high potential for flooding. Charge battery-powered devices when electricity is available; restrict the use of cellular phones to emergencies only. Power down mobile devices when not in use. Keep important documents and necessary medications in waterproof containers.
