HAZARDS AFFECTING LAND

Key messages for Beryl can be found in the Tropical Cyclone

Discussion under AWIPS header MIATCDAT2 and WMO header WTNT42 KNHC.

WIND:

Hurricane conditions are expected in the hurricane warning area beginning early Monday morning.  Potentially catastrophic wind damage is expected where the eyewall of Beryl moves through portions of the Windward Islands, with the highest risk of the core in St. Vincent and the Grenadines, and Grenada. 

Wind speeds atop and on the windward sides of hills and mountains are often up to 30 percent stronger than the near-surface winds indicated in this advisory, and in some elevated locations could be even greater.

Tropical storm conditions are expected in the tropical storm warning area starting late tonight, making outside preparations difficult or dangerous.

Tropical storm conditions are possible within the watch area starting late tonight.

STORM SURGE: 

A life-threatening storm surge will raise water levels by as much as 6 to 9 feet above normal tide levels in areas of onshore flow near where the eye makes landfall in the hurricane warning area.  Near the coast, the surge will be accompanied by large and destructive waves.

RAINFALL:

Hurricane Beryl is expected to produce rainfall totals of 3 to 6 inches across Barbados and the Windward Islands through Monday. Localized maxima of 10 inches is possible, especially in the Grenadines. This rainfall may cause flash flooding in vulnerable areas.

For a complete depiction of forecast rainfall and flash flooding associated with Hurricane Beryl, please see the National Weather Service Storm Total Rainfall Graphic, available at hurricanes.gov/graphics_at2.shtml?rainqpf 

SURF: 

Large swells generated by Beryl are expected across Windward and southern Leeward Islands during the next couple of days. 

These swells are expected to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
