97L BECAME TROPICAL STORM ERIN THIS MORNING AUG 11, 2025

Looking at this climb in the track of Erin, it does not seem like a tropical cyclone that would go further west like most that pass over the northern Leeward. However, I will monitor since during Irma 2017 the models said it would turn northwest, and high pressure built over the storm, and it tracked further west. This is in no way an Irma track, so don't get excited by what I am saying here.

Irma is presently inside a moist environment, which is what it needs to develop. However, there is a small area of increasing wind shear that is presently affecting Erin, and I have noticed the storm activity diminishing some at this time. Erin will have some struggles along the way, as it moves through cooler sea surface temperatures, but as Erin moves near the Northern Leeward Islands or as it passes to the north of the northern Leeward, the water temperature are much warmer. 

Erin is a compact storm, and usually those small storms turn out to be powerful storms, like Andrew, who was a small and tightly wound storm. So we will continue to monitor and report on Facebook and here.

...TROPICAL STORM ERIN FORMS JUST WEST OF THE CABO VERDE ISLANDS...

2:00 PM CVT Mon Aug 11 Location: 17.4°N 28.0°W Moving: W at 20 mph Min pressure: 1004 mb Max sustained: 45 mph

Plenty of dry air ahead of Erin but the storm is inside a moist environment helping with some development. In this image Erin seems to be weakening due to wind shear in the area at this time.
