Mid-Level Dry Air could always be an issue still.

The deep IR is probably a sign of things to come Cape Verde-wise.

Well that depends on what you're expecting from a depression. That microwave imagery actually looks quite organized for a depression. It has banding going into a common center. This looks all-systems-go to me.

Luis, I don't think this question is off topic: Where is everyone getting the info that says the latest a Hurricane ever developed is September 12th? Right off the bat I know that 1914 had only 2 TCs and neither was a hurricane. Do you know what gives?

I'm not quite sure, but I think it in reference to the satellite era.

[WeatherGuesser]

Yeah, the articles all mentioned that.

Since the dawn of the satellite era in the mid-1960s, Feltgen said the latest date for the first hurricane to arrive was set by Gustav when it made its debut on September 11, 2002.

If this year's first hurricane comes anytime after 8 a.m. EDT on Wednesday, it would replace Gustav as the modern-day record holder, Feltgen said.

So, mid-day Wednesday would be fine.

[OuterBanker]

If you think about it, without satellites you could never verify the lack of hurricanes.

[WeatherGuesser]

The 1914 season is one of only two that did not produce any hurricanes (the other being the 1907 season).

http://en.wikipedia.org/wiki/1914_Atlan ... ane_season

So, I guess they're only including seasons that actually had them as far as the latest generation dates.

[HURAKAN]

Since the satellite era, 2013 is the 3rd (so far) latest to have the first hurricane of the season. Before satellites, due to the lack of coverage over the entire basin, its very difficult to have an accurate record.

Before satellites, some storms that were major hurricanes may have been missed entirely, such as Fred and Julia...

Agree

Latest infrared

Latest ASCAT pass

[galaxy401]

Is there a chance this storm could stay south of Cape Verde and turn north once it passes the islands?
