UPDATE: Possible tropical system drenches South Florida

Update 8 p.m.: The weak low-pressure area over Florida is interacting with an upper-level low to produce a large but disorganized area of cloudiness and showers extending from the northwestern Caribbean northward through most of the state, according to the National Hurricane Center in Miami.

Environmental conditions appear to be marginally conducive for some additional development before the upper-level winds become unfavorable early next week, according to the center’s 8 p.m. tropical weather outlook. The chance of a tropical system forming over the next five days is 40 percent.

Regardless of development, the system is likely to produce locally heavy rainfall over portions of western Cuba, the Florida Keys, and the Florida peninsula during the next several days while the system moves northwestward to northward, according to the NHC. The next tropical outlook will be issued at 2 a.m.

UPDATE: Harvey now a tropical wave, Florida in path of weak system

11 p.m. UPDATE: Former Tropical Storm Harvey has degenerated into a tropical wave as it moves quickly toward the west near 22 mph, according to the National Hurricane Center’s 11 p.m. advisory. Maximum sustained winds are near 35 mph.

No additional advisories will be issued unless regeneration occurs or if tropical cyclone watches or warnings are required for land areas. The remnants are expected to move westward across the central Caribbean Sea on Sunday and across the western Caribbean Sea toward Central America on Monday.

Tropical Weather Outlook

8 p.m. UPDATE: Tropical Storm Harvey has weakened to a depression as it speeds west through the Caribbean at 22 mph, according to the National Hurricane Center’s 5 p.m. advisory.

At 5 p.m., Harvey’s center was about 225 miles north-northwest of Curacao with top sustained winds around 35 mph. Some slow strengthening is possible during the next couple of days, and Harvey could regain tropical storm status Sunday.

A turn toward the west-northwest is expected Sunday night or Monday. On the current track, the center of Harvey will move across the central and western Caribbean Sea through Monday. The next advisory will be issued at 11 p.m.

Meanwhile, showers and thunderstorms remain disorganized near a trough of low pressure a couple of hundred miles north of the northern Leeward Islands, according to the National Hurricane Center in Miami. There’s now a 20 percent chance of development, down from 30 percent at 2 p.m.

Environmental conditions are not expected to be conducive for development during the next couple days while it moves west-northwest at 15 to 20 mph. It still could develop as it nears the northern Bahamas or Florida around the middle of next week. The next tropical outlook will be at 2 a.m.

Tropical Weather Outlook

2 p.m. UPDATE: The low pressure system about 250 miles north-northeast of the northern Leeward Islands continues to produce disorganized showers and thunderstorms, but its chance of development over the next five days has been lowered to 30 percent. The system is moving west-northwestward at about 20 mph, and it could become more organized early next week when it nears the Bahamas. The next tropical outlook will be at 8 p.m.

Meanwhile, Harvey is hanging on to tropical storm status as it loses its organization and heads west through the central and western Caribbean Sea. Maximum sustained winds are 40 mph as it speeds along at 22 mph. Watches may be required later today for portions of northern Nicaragua, northern Honduras, Belize, and the Yucatan Peninsula of Mexico. The next advisory from the National Weather Service will be issued at 5 p.m.
