Good morning everyone!
I wanted to make known again, I will be on vacation during the “peak” of the hurricane season (AUG. 29 – SEP 09), on an Alaskan cruise. I will not have the capability to update during that time. Please refer to the NHC. You’ll note various links underneath the header/banner on the page such as the National Hurricane Center, Active Watches and Warnings NWS Hazard and Warnings Display, Satellite and Radar Page (etc.) These are linked to their respective sites and should provide you with ample information.
IF anyone would like hurricane preparedness information, and information on pet friendly shelters, please email me with the subject line HURRICANE PREPAREDNESS.

The Tropical Atlantic is beginning to wake up. Satellite imagery this morning still indicates notable counterclockwise rotation, just south of the Cape Verde islands. I had noticed this yesterday as I was canning through some forecast parameters on my lunch break. The NHC has issued a LOW (20%) probability for development during the next 5 days, however it appears the are looking at the area of convection behind this spin-up, as they mention in their 5 day outlook, a wave is supposed to exit the coast later this weekend.
WEATHERNERDS EATL SATELLITE LOOP (INFRARED, VISIBLE, AND WATER VAPOR)
CLOSEUP AFRICASAT (TROPICAL WAVE OVER AFRICA)
NHC 5 DAY GTWO (LINKED)
The only thing I can come up with looking at this is, the wave over Africa may catch up to the area of vorticity south of the Cape Verde islands and consolidate. It is noted that the wave over Africa does have westward movement, and the area south of Cape Verde has been pretty much quasi-stationary. However, the strongest vorticity is only indicated at the mid levels with the area south of Cape Verde.
CIMSS 700 MB AND 500 MB VORTICITY
Regardless of which area is targeted, analysis of forecast conditions over the MDR indicate that conditions become more favorable in about 96 hours from 06Z this morning (give or take 12 hours) for slow development to occur. Both the ECMWF and GFS indicate low pressure to develop, with the GFS being the quicker of the two. So, bearing in mind the timestamps in the model graphics, BOTH models indicate the forecast of ample moisture in the relative humidity forecast up through the mid levels (minimum of 60% RH required), high PWAT (Precipitable Water) values, and a favorable, radial wind shear pattern over the center of the supposed low pressure area (not to be confused with 200 mb radial outflow pattern). The 200 mb streamline forecast does however indicate a diffluent upper pattern.
ECMWF AND GFS MSLP NORMALIZED ANOMALY FORECAST
ECMWF AND GFS MID LEVEL RELATIVE HUMIDITY FORECAST
ECMWF AND GFS PWAT FORECAST
ECMWF AND GFS SHEAR FORECAST
The ECMWF EPS cyclone formation probability forecast has increased the probability of a tropical depression during the next 4 – 6 days
ECMWF EPS CYCLONE FORMATION PROBABILITY FORECAST
Based on my analysis of the forecast parameters, IF they come to fruition and remain, we should see an INVEST designation in a few days, and quite possibly a tropical depression. It appears the return to activity is playing inline with the update CHI200 anomalies and MJO forecast, which indicates a phase 2 pattern in about 4 days.
JMA CHI200 ANOMALIES FORECAST UPDATE 06 – 12 AUG
13 – 19 AUG
20 AUG – SEP 02
JMA AND BOM PHASE SPACE DIAGRAM FORECAST
I will continue to monitor everything for any significant changes over the tropics, and will update when able.
Elsewhere, I do not expect Tropical Storm formation during the next 5 days.
