TROPICAL WEATHER DISCUSSION FOR NORTH AMERICA...CENTRAL
AMERICA...GULF OF MEXICO...CARIBBEAN SEA...NORTHERN SECTIONS OF
SOUTH AMERICA...AND ATLANTIC OCEAN TO THE AFRICAN COAST FROM THE
EQUATOR TO 32N. THE FOLLOWING INFORMATION IS BASED ON SATELLITE
IMAGERY...METEOROLOGICAL ANALYSIS...WEATHER OBSERVATIONS...AND
RADAR.

BASED ON 1200 UTC SURFACE ANALYSIS AND SATELLITE IMAGERY THROUGH
1645 UTC.

...TROPICAL WAVES...

AN ATLANTIC TROPICAL WAVE IS ALONG 25W/26W S OF 14N MOVING W
NEAR 20 KT. VISIBLE SATELLITE IMAGERY CLEARLY INDICATES CYCLONIC
TURNING NEAR 8N-9N. THE MIMIC-TPW ANIMATION DEPICTS A MOISTURE
SURGE BETWEEN 21W-26W. LOW-LEVEL SATELLITE DERIVED WINDS AS WELL
AS ASCAT DATA SUPPORT THE AXIS POSITION. CLUSTERS OF SCATTERED
MODERATE/ ISOLATED STRONG CONVECTION ARE FROM 7N-9N BETWEEN
25W-27W AND FROM 10N-11N BETWEEN 23W-27W.

Impressive looking wave, but the earliest I can remember one of these actually doing anything was Bertha, and that was around the 4th of July holiday.

Bertha looked like a TD coming off Africa.


It'd be interesting, probably not rising to the level of irony, if this year's Bertha was an unusually early CV storm that came off around the 4th of July weekend.

[KWT]

Well yet another wave that appears to be developing a circulation around 25-30W, thats the second in the last 7 days and all in June as well. If the trend carries on we are eventually going to see one of those spin ups really get going, I wouldn't be all that surprised if we get a CV storm earlier then normal.

Anyway still got decent convection with it and there does appear to be circulation but we shall see what happens with it, I suspect nothing and a similar sort of thing that happened to the last wave awaits this one.

[curtadams]

Looks like the GFS predicts the same thing as the last wave - a tropical system too weak to meet the official TD designation separates from the ICTZ, enters a area of SAL with high shear, and fizzles.

Intense,Large, high latitude wave about to emerge.. see how long it can hold up after exiting the coast

[KWT]

Wow that wave has really exploded in terms of convective strength overnight as it got towardsd the coast. As you say its also at a fairly high latitude so whilst nothing is likely to happen have to admit its a large wave. Mid-Atlantic wave seems to have weakened and most of that convection is probably due to the ITCZ anyway I suspect.

[Meso]

These waves seem to be coming in quick succession too,which means that if shear lets up something should get going.Since the waves ahead should be creating a moist environment while the waves behind will help with the SAL.If it continues like this there is likely to be quite an active Cape Verdes season.SSTs off the coast of Africa have also been very hot over the past months

Yeah Meso, it's what i was saying in most of my lasts posts, at this rate we should see much more surprises, and why not an earlier CV season as you well said it, and if you look at the SAL map, SAL has fairly diminished there's 24h approximately, so maybe more conducives for this one than his predecessor
