Update: 10:33am ET- Subtropical Storm Jerry Forms, No Threat
Subtropical Depression 11 has been upgraded to Subtropical Storm Jerry. The Jerry named has now finally been used after a frustrating few days last week with the Florida system thinking it would become “Jerry” then.

Up Early For the More Active Tropics This Morning
Kind of busy for a Sunday morning post, as there are several area’s in the Tropical Atlantic basin showing signs of Tropical Depression development, and one new Subtropical Depression as well. First up is newly developed Subtropical Depression 11, located in the north central Atlantic about 1000 miles west of the Azores (satellite image) very far from any land. TD11 is expected to become more tropical later today and possible reach Tropical Storm Status. This system might actually become Tropical Storm Jerry after waiting for days for the last system near Florida to become Jerry, but never did. This system is only a threat to shipping.
Deep Tropics Becoming Busy - Invests 96L / 97L
Now for the more interesting tropical systems this morning out there trying ramp up the peak of the hurricane season a little late. Becoming more active out near the Cape Verde Islands and central Atlantic. Tropical disturbance Invest 97L, located a few hundred miles east of the Windward Islands is becoming much better organized this morning with a increase in convection. This system could become a Tropical Depression in the next 24 hours or so as it tracks westward towards the islands and the eastern Caribbean. This system will have top be watched as it could become a possible threat down the road if it develops and remains organized.
Current Tropical Track Model Plots
- Invest 94L Gulf
- Invest 96L Central Atlantic
- Invest 97L Cape Verde Islands
- Subtropical Depression 11 N-Central Atlantic
Then there’s Invest 96L, located just southwest of the Cape Verde Islands. This tropical system looks to be close to becoming a Tropical Depression soon as it too tracks westward. This could become a hurricane threat to the Lesser Antilles down the road if it remains on a lower track across the central Atlantic. Both Invests 96L-97L could become interesting features out there in the coming week or two as we move into late September here in hurricane season 2007. I will be monitoring both disturbances closely.
Southern Gulf of Mexico / Yucatan System
Invest 94L is now moving over the Yucatan Peninsula and expected to move into the southern Gulf later today. A possible recon mission might fly out if things look like they are organizing more with the system. This morning the disturbance looks some what elongated, but has some decent convection associated with it. This will have to closely watched into the new week as it could become a Tropical Storm and threaten the northern Gulf coast in a few days. I’ll keep you posted.
Could Become Real Active Soon
So, 4 area’s this morning to talk about in the tropic’s, 3 invests and one new Subtropical Depression. Could we see Tropical Storms Jerry, Karen, Lorenzo, and even maybe Melissa in the coming week? We’ll have to see if these systems can hold together, and if any of them become major threats down the road. More to come on all of these systems as they develop this upcoming week. Stay tuned.

Great post, Jeff. You really should consider teaching.
THanks Dew. Never thought of teaching before. I do speak at local K-5 schools about hurricanes and tornadoes each year.
TD11 now Jerry
You are good at what you do.
