It has never appeared in NRL


NHC just ran more model guidance on it. SHIP takes it from 20 kts at 00hrs to 18kts at 12hrs to 0kts after 12 hrs. Never seen anything like this (as an invest)

From 2 PM TWO:

A TROPICAL WAVE LOCATED ABOUT 850 MILES WEST OF THE SOUTHERN CAPE
VERDE ISLANDS IS PRODUCING DISORGANIZED SHOWERS AND THUNDERSTORMS.
UPPER-LEVEL WINDS ARE NOT FAVORABLE FOR DEVELOPMENT. THERE IS A LOW
CHANCE...LESS THAN 30 PERCENT...OF THIS SYSTEM BECOMING A TROPICAL
CYCLONE DURING THE NEXT 48 HOURS.

Waste of an invest IMO. Even in the best of years, Cape Verde storms in late October are rare. 94L has a better chance of becoming stronger than Wilma than this becoming a tropical depression IMO.

Yep, there is a naked swirl there - in 50-60 kts of shear. Development chances are <30%, so I agree with NHC. Probably closer to .01% than 30%, though. But I guess they saw the rotation and had nothing better to do than to run a few models on it. No harm done.

At least it has a circulation, in the WPAC it seems almost every cloud gets an invest status

No mention of this system at the 8 PM Tropical Weather Outlook.It means the invest will be deactivated.

Guess the boys at the NHC got tired of downloading Facebook and wanted to look at something. This has got to be one of the most pathetic invests in history. :roll:
