HURRICANE IGOR
From StormW's blogpost this morning:

Quote:Good morning!


Elsewhere, a tropical wave lies just to SSE of the Cape Verde Islands, and will be monitored for development over the next 96 hours.

The African wave train remains active, and any waves that exit into the Atlantic WILL have to be monitored, as the shear forecast map, for the 4th day in a row, indicates a series of upper level anticyclones to develop as waves enter the Atlantic.

Elsewhere, Tropical Storm formation is not expected through Tuesday.

[b]Possible Development Off Of West Coast Of Africa Over Next 7 to 10 Days:[/B

The next item to really monitor will be a tropical disturbance now tracking off of the coast of Africa and another tropical disturbance slated to track off of the coast of Africa later this week. Pretty much all of the global model guidance forecast this to become our next two tropical cyclones in the next 7 to 10 days with Igor potentially developing over the next 2 to 3 days in the far eastern Atlantic and possibly Julia to develop in the far eastern Atlantic early next week. The synoptic forecast over the next couple of weeks features a possible weakness in the ridge of high pressure near 60 West Longitude and this could cause both systems to curve northward before reaching the Lesser Antilles. With that said, it should be noted that the latest European model run forecasts Igor to be located just northeast of the northern Leeward Islands 10 days from now that looks to possibly miss this weakness. It needs to be added that the European model hasn’t done too well lately as it has been recently too strong with the forecast of eastern US high pressure ridges.
I will be monitoring things off of the coast of Africa closely this week and will keep you all updated.
