Looks like Martinica or especially Guadeloupe could be under an yellow alert given Meteo-France. Stay tuned, i will keep your informed if any alert is requiered.
I will be glad today to know the weather conditions in the others islands of the Windwards my carib friends (Martinica, Dominica)... due to the approach of this twave:) Don't forget to post any infos about your island!

When my husband said we had a Large pop-up south of us I thought he meant we had rain approaching. Then I saw that blob. Stay dry and let us know what's going on Gusty.

OK tkanks for the info :) I will keep your informed if anything happens in Guadeloupe...as usual for sure :wink:
Stay safe too and make observations we never know in the tropics, Mother Nature has always surprises in store...

The Atlantic is quiet; remembering Hurricane Hugo 20 years later


Posted by: JeffMasters, 14:30 GMT le 14 septembre 2009

Considering that the third week of September is usually one of the busiest weeks for Atlantic hurricanes, the tropical Atlantic is very quiet today. The remains of Hurricane Fred continue to generate sporadic bursts of heavy thunderstorm activity over the middle Atlantic Ocean. Dry air and prohibitively high wind shear of 40 knots today will continue to prevent regeneration, and none of our reliable models are calling for Fred to regenerate this week.

Satellite imagery and this morning's QuikSCAT pass show a small circulation associated with a tropical wave about 100 miles south of the Cape Verdes Islands, just off the coast of Africa. The wave has only a small amount of heavy thunderstorms, on the west side of the circulation, and QuikSCAT showed only 20 mph winds in the region. None of the models develop this wave, and it is probably too small to develop into a tropical depression. Still, it is worth keeping an eye on.

Tropical storm development is possible this week along a frontal zone stretching from Florida to the waters between the Bahamas and North Carolina. However, wind shear will be relatively high in this region, and anything that develops may end up being extratropical in nature, and would likely move northeastward out to sea.

The GFS model is predicting development of a new tropical wave coming off the coast of Africa late this week.


Twenty years ago on this date
On September 14, 1989, I arose at dawn to prepare for my flight to Barbados to meet Hurricane Hugo. First order of business was to flick on my weather radio and check out the latest advisory for the hurricane. Category 1, 90 mph winds, headed west-northwest at 15 mph. As expected. Next order of business, call in to the hurricane hunter hotline and listen to the mission plan. "We are planning a two-plane deployment to Barbados today, departing at twelve hundred hours. Crew assignments are as follows..." On schedule, and no crew changes. I finished packing my bag and headed to Miami International Airport to fly out to meet Hurricane Hugo.


As our big P-3 Orion hurricane hunter plane droned over the Caribbean towards Barbados, we didn't have any means to check on what the hurricane was doing. I could only guess how strong a hurricane might greet us when we landed. We landed uneventfully at Barbados' Grantly Adams International Airport shortly after dark, and disembarked from the aircraft. As we walked across the tarmac towards the terminal, we were suddenly confronted by the flashes of cameras as a group of reporters documented the arrival of the "daredevil" Hurricane Hunters. We'd never had a welcoming committee at one of our landings before, and all smiled and laughed at our sudden fame. It seems Hurricane Hugo was big news in the Caribbean. I quickly found out why, when I got to the weather briefing room at the terminal. Hugo had rapidly intensified during the day, and was now a major Category 3 hurricane with 115 mph winds. With Hugo still over a day from the islands, the hurricane had plenty of time to intensify further. Barbados was well south of the expected path of the hurricane, and was thus a safe base of operations, but the mood on the island was frightened and electric. It had been nine years since the last major hurricane smashed through the Lesser Antilles Islands--Hurricane Allen of 1980. The roll call of the most notorious hurricanes to devastate the islands of the Lesser Antilles--Allen of 1980, David of 1979, Inez of 1966, Cleo of 1964, Flora of 1963, and Donna of 1960--would soon be adding a new name.


Figure 3. The front page story of the September 15, 1989 issue of the Barbados Weekend Nation newspaper featured our arrival the night of September 14, 1989, at Barbados' Grantly Adams International Airport. From left to right: Alan Goldstein (electronic engineer), Dave Turner (pilot), Gerry McKim (pilot, partially hidden), Jim Roles (electronic engineer), Neal Rain (electronic engineer), Jeff Masters (flight meteorologist), Terry Schricker (electronic engineer), Sean White (Navigator), Lowell Genzlinger (pilot), Jack Parrish (flight meteorologist).

The entire Caribbean was in an uproar. Thousands of boats across the Caribbean set sail to seek safe harbor. Tourists besieged besieged airports, seeking to escape the hurricane. Stores throughout the Caribbean islands along Hugo's projected path reported shelves stripped of provisions as residents prepared for the Caribbean's most deadly fury--a fully mature Cape Verdes hurricane. And tomorrow, my plane with fourteen Hurricane Hunters and one reporter would be the first humans to encounter Hugo.

Tomorrow's post
By now, many of you have read my story of my flight into Hurricane Hugo on September 15, 1989. Tomorrow, I'll present the story of the flight as seen through the eyes of reporter Janice Griffith of the Barbados Sun.

Hi Barbara.Nothing to worrie about but scattered showers will fall in the islands as it moves to the NW.Never say never in the tropics especially in mid september so even as the upper levels dont favor tropical cyclone formation,we have to watch it just in case.

Just spoke to my family in the north of the island of Barbados and they are experiencing lots of rain, thunder and lightning. Meanwhile about 18 miles south of their location I have brilliant sunshine. Below is the latest from our met office here.



Severe Weather Advisory

The combination of light winds, an abundance of low level
moisture and strong daytime heating is producing local
moderate to heavy showers and thunderstorms over some
Northern, Central, Western and Northwestern parts of the
island.

As a result A Flash Flood Warning is in effect for the
above mentioned areas.

Residents should be on the alert and take the necessary
precautions.

This WARNING will remain in effect until 6:00 p.m. today.

I think our meteorologist, David Best, said last night that the system presently in our area is a combination of the tail end of a TW, a low level trough and the ITCZ. I heard just a bit of thunder earlier but we in the south of the island have hardly any rain so far while many parts in the northwest have been experiencing pretty bad flooding.

However, having just peeked outside, it looks like we in the south are about to get lots of rain too! :eek:

Thought we might have escaped this one in the south but looks as though it is coming in from the direction of South Point just looking at it coming off the sea now

Yep. And the thunder is starting up again. Judging from this water vapor loop, moisture is definitely increasing all around us. I’m afraid I’m going to have to shut down the computer and unplug it to protect it from power surges due to lightning (the thunder is starting to get louder).

Bye for now.
