If we have high pressure over Bermuda, the East Coast gets it.

It's hard to believe it's been 10 years since Katrina. What is forgotten is that it caused significant damage in the Ft. Lauderdale area before growing into the monster it became when it hit the Gulf.

I followed it from FLA to Gulfport. The day before landfall my cameraman and I were staying in the Holiday Inn on the beach. We evacuated to an old HoJo's near the airport in Mobile. Turned out to be a good thing, because most of the Holiday Inn was under water. Mobile was bad enough. The roof the HoJo's was torn off and the downtown was flooded. The next day we headed north and saw the destruction all the way to Montgomery.

The ten days that we covered the storm were both awe-inspiring and terrifying at the same time. Glad I'm not doing that today.

Looks like it's going over Cuba to the gulf coast of FL.

Erika wants to come get cozy with me here in Tampa.

***** needs to get back on her corner.

It looks like it will probably be quite weak by the time it gets to you, but you could get a lot of rain.

Well, yes. It may not even come at me, with the way the projections have steadily shifted west. We don't particularly need the rain though, either... had some pretty widespread flooding just 3 weeks ago or so.

Erika has dissipated. http://www.nhc.noaa.gov/text/refresh.../291331.shtml? There still will be rain, of course.

Now a hurricane. This is only the third hurricane to ever affect the cape verde islands and maybe the first to ever make landfall on one of the islands.

It looks like Freddy isn't going to do much more hacking.

It's interesting that this is the third consecutive TS to peter out before reaching the US this season. Not that I mind.

That would be in line with the strong El Nino still forecasted to continue through the early winter months.

Can you explain why those are related? It sounds almost like you're saying there are pressure centers over the continent that act like a sort of Maginot Line and break up the storms as they come in.

In an El Nino you get strong westerly upper-level winds across the Caribbean and tropical Atlantic. This rips the top of the thunderstorms off, so they can't develop, which prevents tropical systems from developing. This year, the wind shear across the Caribbean has been at record high levels for most of the summer.

Interesting. Thank you.

Interesting. Thank you.

To add to his point, wind shear is the difference in wind speed at the surface to to upper levels of the atmosphere. If the wind speed is only 10 knots at the surface but 50 knots in the upper atmosphere, you get 40 knots of shear that will keep the thunderstorms away from the center of the storm effectively killing it or forcing it to transition into a more traditional system that develops over land.
