Tropical Update

Florence weakens to a category two hurricane. Florence is centered about 1115 miles ESE of Bermuda and moving NW at 10 mph. A turn toward the WNW and west with a decrease in forward speed is expected through Saturday. Florence may begin to move faster toward the WNW over the western Atlantic early next week.

Maximum sustained winds have decreased to near 105 mph with higher gusts. Additional weakening is forecast during the next day or two. However, Florence is expected to remain a hurricane and likely reintensify over the weekend.

We are tracking a broad area of low pressure several hundred miles WSW of the Cabo Verde Islands. There are no indications yet that the system has a well-defined center of circulation. However, environmental conditions are conducive for development, and a tropical depression is expected to form within the next few days while the system moves slowly west or WNW across the tropical Atlantic Ocean.

* Formation chance through 48 hours: High (70%).

* Formation chance through 5 days: High (90%).

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 west over the far eastern tropical Atlantic Ocean.

* Formation chance through 48 hours: Low (10%).

* Formation chance through 5 days: Medium (50%).
