Tropical 2025 Tropical Thread

For the first time in weeks, the latest Euro Weeklies actually has a week forecasted to be slightly above the 2005-2024 average in the ATL basin. It’s for Aug 11-17:

It has that week at 110% of 2005-24 avg:

Just two runs ago it had only 60% of 2005-24 avg:

For the MDR lemon that’s been in the TWOs for a bit:


Tropical Weather Outlook

800 PM EDT Sat Jul 19 2025

For the North Atlantic...Caribbean Sea and the Gulf of America:

Central Tropical Atlantic:
A tropical wave located about 1000 miles west-southwest of the
Cabo Verde Islands is producing disorganized showers and
thunderstorms. Environmental conditions appear marginally conducive
for gradual development during the next few days as the system moves
westward to west-northwestward around 10 mph. By the middle of next
week, environmental conditions are forecast to become unfavorable
for further development.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 7 days...low...20 percent.

Shear going to kill it if it does form.

Thanks RC. Also, though climo says MDR chances start rising notably in late July, it’s still usually inactive this early based on looking back decades. This is despite recent years possibly giving a more bullish impression.

Although warm, it currently isn’t as warm in that region as the prior two summers.

Yeah we still got a month to go before the real season starts imo

Not to say we can't get something but I'm talking about a legit storm
 
Regarding Invest 94L in the MDR: 8PM TWO sounds significantly more bullish than prior ones though the % rose only from 10 to 20:

For the North Atlantic...Caribbean Sea and the Gulf of America:

Central Tropical Atlantic (AL94):
A small area of low pressure has developed from a tropical wave in
the Central Tropical Atlantic, about 900 miles east-southeast of the
Lesser Antilles. Shower and thunderstorm activity has recently
become more concentrated near the center, and environmental
conditions are generally favorable for some additional development
over the next day or so while the system moves west-northwestward at
10 to 15 mph. By the middle of this week, environmental conditions
are forecast to become unfavorable for further development.
* Formation chance through 48 hours...low...20 percent.
* Formation chance through 7 days...low...20 percent.

So, this Andy Hazelton tweet is sort of agreeing with what Eric Webb just had said about an expected quiet August into early Sept. Note, however, that Andy said “I’m kinda of the same opinion that August may be quiet in the Atlantic”, which isn’t a forecast since August “may be quiet” in any year. A forecast would say something like “August will be quiet”, “I expect August to be quiet”, or “August will likely be quiet”.

The euro had a couple decent looking waves traverse the MDR but nothing going yet. Some signs of life though for sure

I sure hope Aug is active. If we have yet another dead season till mid/late Sept then NC is out of the game as the winter pattern will have arrived and anything in the ATL recurves east of Bermuda.
