Good evening 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 tropics still remain very quiet as of this evenings analysis. You’ll note there is still a significant amount of dry air in the water vapor loop image.

I know a lot of you are anxious for activity to pick up, as am I. However, we are still in that portion of the hurricane season where the “climatological” ramp up doesn’t really begin until after AUG. 05.

I know we were expecting an uptick toward the end of this month, however, the forecast CHI200 anomalies pattern and MJO phase space diagrams did not pan out yet, as was shown in the previous forecast. Based on what have seen over this past week, the modeling was definitely overdone as far as both coverage and amplitude of the signal. However, ensemble models have updated (JMA is still the same from Thursday, as it only updates on a weekly basis), and the JMA and ECMWF EPS systems have become in better agreement as far as amplitude and coverage of the anomalies. Based on this, the forecast still indicates the MJO going into a phase 2 signal, which is the more favorable phase for tropical activity out of the 8 phases. Once again, IF (and I stress IF) these signals come to fruition, we should see the African wave train begin to roll, in which I still believe we will see a very active season. Maybe not hyperactive, however I do believe I should make at least the low end of my seasonal forecast. I know as dead as it has been all of July, folks my be having doubts, and could in fact be correct. However, I am going to point out some of the “signals” that point to a busy season. I will compare them to the hurricane season of last year, to which we had a total of 21 named storms.

The following are the current SST anomalies for the Tropical Atlantic. The setup you see, is what we refer to as the Atlantic Ocean Tripole (warm over cool, over warm). This profile allows for maximum net lift over the MDR. This is a favorable development signal. You’ll note, this was not present during the same time in 2021.

The updated forecast for the IOD (Indian Ocean Dipole) still indicates we remain in a fairly negative IOD (colder anomalies western Indian Ocean, warmer in the eastern Indian Ocean), which should negate subsidence over central Africa, westward. The following graphics indicate a negative IOD currently, and a less negative IOD in 2021 during the same time

Based on update ENSO information, we are currently in a neutral, strong cold bias pattern, however some La Nina like signals still remain in the atmosphere. The majority of the climate modeling however indicates a very good chance at returning to a La Nina pattern by Oct. La Nina did weaken during the month of June, however it appears cooler anomalies have made a comeback.

Now, compare the NINO 3.4 region for the same period of 2021

The stronger the cooler anomalies, the less wind shear becomes over the Atlantic basin.
The final positive factor I wanted to point out is, TCHP / OHC (Tropical Cyclone Heat Potential / Ocean Heat Content) is almost off the charts, especially over the W. Caribbean and central GOMEX. SST’s alone are warm enough from 45.0 degrees west, westward, to allow development. The TCHP from the same point, will not only sustain a hurricane, values are high enough to support a major hurricane. Based on my past research, values of 50+ are enough to accomplish this. So, based on all of these favorable factors I have gone over, I am lead to believe we should still witness a fairly active season, once it ramps up.
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.
