Tropical Storm Lisa forms as Karl stays steady in Atlantic

MIAMI, Sept. 20 (UPI) — A tropical depression quickly became Tropical Storm Lisa west of Africa on Tuesday as Tropical Storm Karl was staying steady farther east in the Atlantic.

Lisa was classified as tropical Depression 13 overnight but strengthened to a tropical storm in the 11 a.m. Tuesday advisory from the National Hurricane Center. It was about 430 miles west of Cape Verde with maximum sustained winds of 40 mph as it moved west-northwest at 12 mph.

Lisa was forecast to continue a westward route over the next 48 hours but the center noted “a marginally moist mid-level environment and the large size of the cyclone are expected to prevent any rapid strengthening from occurring.”

This 12th named storm marks the first time in three years the Atlantic has reached the “L” in the alphabet. In 2013, there were 15 tropical cyclones, including one late unnamed system in December.

Karl was about 855 miles east-northeast of the Leeward Islands and was traveling west-northwest near 17 mph with wind gusts of 40 mph, according to the National Hurricane Center. Little change is forecast during the next 24 hours but some strengthening is predicted the next day due to warmer waters as it turns to the northwest.

“The official intensity forecast continues to show Karl as a hurricane in the three- to five-day range, but the updated forecast has been nudged downward slightly based on the latest guidance,” the center said.

It’s heading north to travel north of the Leeward Islands and Puerto Rico, and away from the United States, but is forecast to come close to Bermuda by Saturday.

The Bermuda Weather Service considers it a “potential threat” and the Ministry of National Security is “closely monitoring the forecast track of the storm,” according to The Royal Gazette.
