Gettin' Some Action

Due to a stubborn Bermuda High, the Intertropical Convergence Zone has been forced south for the first 6 weeks of the 2007 hurricane season. Since the zone is a key ingredient in the witches brew of tropical storms, its being forced into the South American coast has created a lull in cyclonic development.

Well, no more. The high is relenting and the ITCZ is slowly moving north. Already there is something brewing just south of Puerto Rico.

Last year's relatively quiet season, i.e. little Gulf of Mexico activity, combined with this years slow start might bring on complacency. It shouldn't. We are now just entering peak hurricane season so it would be a good time to check all your preparations.

This morning's science moment brought to you by the letter H and the number 42.

Is it wrong that I'm wishing for lots of subdued tropical depressions which bring good, soaking rains?

Jmac, given I have a pond in south Georgia that is two feet low, I would give anything for a good depression with about four days of steady rain.

I have grandparents in Tampa area who need a push to move up to Georgia. I mean if one has to hit, that would be the spot I'd choose.

And yes, I'd also choose for it to stay just far enough south to spare your relations down there.
