Tropical Cyclone 13L (Lee)
LEE BECOMES A CATEGORY 5 HURRICANE…DANGEROUS BEACH CONDITIONS EXPECTED TO DEVELOP AROUND THE
WESTERN ATLANTIC THROUGH EARLY NEXT WEEK
According to the NHC advisory number 11…
Lee is moving toward the west-northwest near 14 mph (22 km/h), and this motion is expected to continue through early next week with a significant decrease in forward speed. On the forecast track, Lee is expected to pass well to the north of the northern Leeward Islands, the Virgin Islands, and Puerto Rico over the weekend and into early next week.
Data from an Air Force Reserve Hurricane Hunter aircraft indicate that maximum sustained winds have increased to near 160 mph (260 km/h) with higher gusts. Lee is a category 5 hurricane on the Saffir-Simpson Hurricane Wind Scale. Additional strengthening is forecast overnight. Fluctuations in intensity are likely over the next few days, but Lee is expected to remain a major hurricane through early next week.
Hurricane-force winds extend outward up to 45 miles (75 km) from the
center and tropical-storm-force winds extend outward up to 140 miles
HAZARDS AFFECTING LAND
SURF: Swells generated by Lee are expected to reach portions of the Lesser Antilles on Friday, and reach the British and U.S. Virgin Islands, Puerto Rico, Hispaniola, the Bahamas, and Bermuda this weekend. These swells are likely to cause life-threatening surf and rip current conditions.
