    African disturbance 92L could develop into tropical depression

    A strong tropical wave (Invest 92L) moved off the coast of Africa last night, south of the Cape Verde Islands. This low has the potential to develop into a tropical depression late this week as it moves westwards at 15-20 mph. The low is under about 10 knots of wind shear, which is favorable for development. Sea Surface Temperatures are about 28C, which is about 2-3C above average for this date, and well above the 26C threshold for tropical storm formation. There is not much African dust or dry air near the storm, but so far the low has not been able to generate much heavy thunderstorm activity. The low has plenty of spin, and has developed some broad, curved bands that are a sign of organization. I can't really find any negatives for development, except for climatology--there has never been a tropical depression that has formed east of 34 W longitude in the first half of July (see the first image I posted in yesterday's July Atlantic hurricane outlook). NHC is giving a low chance (less than 20%) that 92L will develop into a tropical depression by Thursday

    Shhh...if we don't talk about it, it won't happen
    You won't cry for my absence, I know -
    You forgot me long ago. Am I that unimportant...?
    Am I so insignificant...? Isn't something missing?
    Isn't someone missing me?
