Tropical wave will soon strengthen into a depression. What Florida should know
The Atlantic Ocean weather isn’t taking Labor Day Weekend off with the development of three disturbances, one of which will become a depression and the strengthening and weakening of Gert and Katia.
Here’s what the National Hurricane Center had to say in its latest advisories.
What’s the forecast for the tropical wave in the central Atlantic?
This tropical wave is about 700 miles west-southwest of the Cabo Verde Islands and is expected to be a tropical depression by sundown Wednesday.
“The low-level circulation has become better defined since (Sunday), with increasing organization in the shower and thunderstorm activity,” the hurricane center said in its 2 p.m. advisory. “Additional strengthening is likely late this week while the system moves westward to west-northwestward at 15 to 20 mph over the central and western portions of the tropical Atlantic.”
It is too soon to say whether this system will have any impact on Florida.
Formation chance through 48 hours: 90%, up from 70% at the last advisory.
Formation chance through seven days: 100%, up from 90% at the last advisory.
What’s happening with Tropical Depression Katia?
Tropical Depression Katia and its 30 mph winds are about 1,045 miles northwest of the Cabo Verde Islands, moving northwest at 5 mph.
There are no warnings or watches in effect for Katia.
“Katia should slowly undergo a clockwise loop during the next two days and be moving more steadily southward by Thursday,” the 11 a.m. advisory said. “Gradual weakening is forecast, and Katia is expected to become a remnant low (Monday night) and dissipate in a few days.”
Gert’s back to being remnants of a storm
This system’s second run as Tropical Storm Gert has ended, the hurricane center noted in its 10 a.m. advisory.
“Gert has dissipated,” the hurricane center said. “Its remnants will continue to rotate around the circulation of Post-Tropical Cyclone Idalia (Monday).”
Gert’s remants still have 50 mph maximum sustained winds. As of 10 a.m., they were about 950 miles northeast of Bermuda and were hustling north-northwest at 29 mph. Tropical storm winds blow up to 70 miles from the system that was Gert.
What’s expected to happen with the disturbance over western Africa?
The hurricane center said in its 2 p.m. Monday advisory that a tropical wave over western Africa is forecast to move offshore in a couple of days.
“Environmental conditions should support some slow development, and a tropical depression could form over the far eastern tropical Atlantic around the latter part of the week while the wave moves to the west-northwest at about 15 mph,” the hurricane center said.
Formation chance through 48 hours: near zero percent.
Formation chance through seven days: 50%, up from 40% at the 8 a.m. advisory.
The remnants of Hurricane Franklin remain a system
What’s left of Hurricane Franklin is a system in the Northeastern Atlantic, a few hundred miles north of the Azores.
“This system could acquire some subtropical or tropical characteristics late this week or this weekend while it moves erratically between the Azores and Portugal,” the 2 p.m. advisory said.
Formation chance through 48 hours: near zero percent.
Formation chance through seven days: 20%.
