Nana now a remnant low, Tropical Depression Omar struggles, four areas to watch in the Atlantic
We are quite active in the Atlantic Basin this evening: A tropical depression, a remnant low and four areas of interest to monitor.
Nana made landfall as a Category 1 hurricane around 2 a.m. on the coast of Belize between Dangriga and Placencia. As of the 11 PM update, it has weakened to a remnant low as it’s moving over land.
Now, the biggest threat is rain leading to flash flooding and mudslides. Rainfall totals will peak near 3 to 6 inches from central to western Guatemala and Chiapas, with isolated amounts near 8 inches.
Elsewhere, Tropical Depression Omar is barely holding onto tropical depression status as it continues to be sheared by high vertical winds. It is moving away from the United States and poses no threat to land.
Otherwise, we have three areas of interest to monitor in the equatorial Atlantic.
The first, dubbed Invest 91-L, is a weak area of low pressure in the central Atlantic is producing disorganized showers and storms. This system is expected to interact with a second tropical wave over the weekend, and it is unclear if the interaction will enhance or inhibit the development of this system while it meanders through the Atlantic.
Right now, the National Hurricane Center is giving it a 40% chance of development over the next 5 days.
A second tropical wave located just off the African coast is expected to merge with the first disturbance over the weekend, leading to a wider area of showers and storms. Development will become more likely as it moves westward through the Atlantic Ocean.
A tropical depression may early next week where environmental conditions are more favorable for development. Right now, the National Hurricane Center is giving it a 70% chance of development over the next 5 days.
Also, as of the 8 PM update, the National Hurricane Center has issued a 20% chance of development within the next 5 days, as shower activity increased throughout the day in association with a non-tropical area of low pressure located in the north-central Atlantic. It will likely weaken as it moves over cooler waters of the north Atlantic.
We have plenty of time to watch as all disturbances are well over 3,000 miles away from Southwest Florida! The next storm name on the list is Paulette, followed by Rene and Sally.
The climatological peak of hurricane season is one week away on September 10th, so it’s no surprise we are seeing a very active Atlantic basin! Trust our Weather Authority team to keep you updated.
