This has a pretty vigorous circulation, and if it stays weak like this until farther west this may need to be watched

the mighty 98L has struck out.

Another wave that DID emerge from Africa and DID get destroyed by 2013.

This is why I doubt the talk about no African waves. We've had plenty, it's not the reason for the season.

[Alyono]

why was this dropped?

The models are starting to develop it now

8 AM Tropical Weather Outlook.

SHOWERS AND THUNDERSTORMS ASSOCIATED WITH A TROPICAL WAVE LOCATED
ABOUT 450 MILES WEST-SOUTHWEST OF THE CAPE VERDE ISLANDS ARE
SHOWING SOME SIGNS OF ORGANIZATION. HOWEVER...FURTHER
DEVELOPMENT...IF ANY...IS EXPECTED TO BE LIMITED DUE TO DRY
AIR...AND ENVIRONMENTAL CONDITIONS ARE FORECAST TO BECOME VERY
UNFAVORABLE IN A COUPLE OF DAYS. THIS SYSTEM HAS A LOW CHANCE...
10 PERCENT...OF BECOMING A TROPICAL CYCLONE DURING THE NEXT
48 HOURS...AND A LOW CHANCE...10 PERCENT...OF BECOMING A TROPICAL
CYCLONE DURING THE NEXT 5 DAYS WHILE IT MOVES TO THE WEST-NORTHWEST
AT ABOUT 10 MPH.
