Some forecasts call for as many as three named tropical systems in the Atlantic next week.

Hurricane Florence is a major hurricane and two other tropical waves west of Africa are displaying increasing signs of development.

Meanwhile, Gordon continues to weaken but is threatening several areas with heavy rain and the potential for flash floods.

Gordon made landfall Tuesday night with 70 mph winds, leading to the death of a child after a tree fell on a mobile home in Pensacola.

In the Pacific, Hurricane Olivia weakened slightly but remains a category 3 hurricane and an area south of Mexico has a 30 percent chance for development over the next five days.

Atlantic

Hurricane Florence

Hurricane Florence should remain a powerful hurricane for several days.

Location: 1,235 miles east-southeast of Bermuda

Maximum sustained winds: 125 mph

Movement: northwest at 10 mph

At 11 p.m., the eye of Hurricane Florence was 1,235 miles east-southeast of Bermuda.

A turn toward the west-northwest with a decrease in forward speed is forecast to begin Thursday night, followed by a turn toward the west by the weekend.

Maximum sustained winds have decreased slightly to near 125 mph, with higher gusts. Florence is a category 3 hurricane on the Saffir-Simpson Hurricane Wind Scale.

Some gradual weakening is forecast during the next 48 hours, with restrengthening possible over the weekend.

Hurricane-force winds extend outward up to 15 miles from the center, and tropical-storm-force winds extend outward up to 90 miles.

Tropical Depression Gordon

Tropical Depression Gordon continues to weaken over Western Mississippi, but the threat of heavy rain and flooding is expected to continue for several days.

This rainfall will cause flash flooding across portions of these areas.

Wind: Wind gusts to tropical storm force may occur in showers and thunderstorms associated with Gordon overnight.

Tropical waves

1. Shower activity associated with a broad area of low pressure centered a couple of hundred miles southwest of the Cabo Verde Islands is gradually becoming better organized.

Environmental conditions are forecast to be conducive for additional development, and a tropical depression is expected to form during the next couple of days while the system moves west-northwestward across the tropical Atlantic Ocean.

Formation chance through 48 hours: 70 percent.

Formation chance through 5 days: 90 percent.

2. A tropical wave is forecast to move off the west coast of Africa on Friday.

Some development of this system is anticipated after that time, and a tropical depression could form over the weekend or early next week while the wave moves westward over the far eastern tropical Atlantic Ocean.

Formation chance through 48 hours: near 0 percent.

Formation chance through 5 days: 40 percent.

Pacific

Hurricane Olivia

Hurricane Olivia continues to move west-northwest.

Location: 1,015 miles west-southwest of Baja California

Maximum sustained winds: 100 mph

Movement: west-northwest at 14 mph

At 11 p.m., the center of Hurricane Olivia was 1,105 miles west-southwest of Baja California.

Olivia is moving toward the west-northwest near 14 mph, and this motion with some increase in forward speed is expected during the next couple of days. A gradual turn toward the west is expected over the weekend.

Maximum sustained winds are near 100 mph, with higher gusts. Some slight weakening is forecast during the next few days.

Hurricane-force winds extend outward up to 25 miles from the center and tropical-storm-force winds extend outward up to 115 miles.

Hurricane Norman

Major Hurricane Norman is still a major hurricane east of the Big Island of Hawaii and tracking west-northwest.

Location: 570 miles east of Honolulu, Hawaii

Maximum sustained winds: 120 mph

Movement: west-northwest at 9 mph

At 11 p.m., the center of Hurricane Norman was 570 miles east of Honolulu, Hawaii.

Norman is moving toward the west-northwest near 9 mph. This motion is expected to continue Wednesday night, followed by a northwestward motion on Thursday and Friday.

On the forecast track, the center of Norman will pass 200 to 300 miles to the northeast of the main Hawaiian Islands on Thursday and Friday.

Maximum sustained winds have strengthened to near 120 mph, with higher gusts, and Norman is a category 3 hurricane on the Saffir-Simpson Hurricane Wind Scale.

Some weakening is forecast during the next 48 hours, although Norman is expected to remain a hurricane through Friday.

Hurricane-force winds extend outward up to 30 miles from the center and tropical-storm-force winds extend outward up to 115 miles.

Large swells generated by Norman will continue to spread from east to west across the Hawaiian Islands during the next couple of days. Large and potentially dangerous surf produced by these swells is expected along east facing shores through Thursday night.

Disorganized showers

A broad area of low pressure centered about 450 miles south- southwest of Zihuatanejo, Mexico, is producing disorganized showers and thunderstorms extending well offshore the southern coast of Mexico.

Upper-level winds are forecast to become more conducive for development, and a tropical depression could form by early next week while the system moves slowly west-northwestward at about 10 mph away from the coast of Mexico.
