Atlantic Goes Into a Brief Lull With Demise of Hermine

The Tropical Atlantic has gone into a brief lull on this Wednesday morning. The last advisory was issued by the National Hurricane Center on Tuesday afternoon for Post-Tropical Cyclone Hermine just off the coast of Long Island, and the tropical disturbance, Invest 92L is not a threat to develop at this time. However, we are still monitoring, Invest 93L in the Far Eastern Atlantic, which could become a depression by the weekend. Let’s take a closer look around.

Let’s take a closer look around the tropics this morning:

Gulf of Mexico

Checking the latest satellite imagery courtesy of NOAA, skies are mostly clear in the Gulf. There are some areas of clouds dotted around the region, but they are scattered at not organized at the moment. No threats here. No development expected for the next 24 to 48 hours.


There are a couple clusters of showers and storms in the Southwestern Caribbean near Nicaragua and Honduras and well as some south of Jamaica. There is also another cluster to the north of Panama. We also have some disorganized clouds and showers associated with Invest 92L, which is currently moving through Hispaniola and the Southeastern Bahamas. Hostile upper level winds as well as the rugged terrain of Hispaniola will make things difficult for Invest 92L to develop over the next several days. No development is expected for at least the next 48 hours.

Atlantic Ocean

Although the National Hurricane Center has a issued its last advisory on Post-Tropical Cyclone Hermine on Tuesday afternoon, there is still a nice swirl of clouds from the decaying system off the Mid-Atlantic coast some several hundred miles due east of say Island Beach State Park in Ocean County, New Jersey.

Some of those clouds have spread over inland portions of New Jersey including Greg’s Weather Center and as far north as Little Falls in Passaic County. Hermine’s remains are expected to meander around the Mid-Atlantic for part of the day today, and then begin to head northeast again. It is also expected to dissipate.

Meanwhile, in the Far Eastern Atlantic, we continue to monitor Invest 93L, which is located near the Cabo Verde Islands. Right now, the tropical wave has disorganized shower and thunderstorm activity associated with it, and no further development is forecast for the next couple of days.

However, low pressure is anticipated to form with this wave, and atmospheric conditions are anticipated to become more favorable for slow development later in the week. We could see a depression form by this weekend. Presently, the NHC is giving Invest 93L a 20 percent chance of development over the next 48 hours, and a 70 percent chance over the next five days.


The conga line of tropical waves heading for the Atlantic from the African continent continues. There is a cluster of showers and thunderstorms over Senegal this morning, and that appears to be the next tropical wave to enter the Eastern Atlantic. behind it, there are more clusters of showers and storms covering Southern Niger, Southeastern Burkina Faso, and much of Nigeria.
