Oh lookie, they have it forecast to hit us TWICE as a hurricane, once in south Florida and then again along the Gulf Coast.

And we all know where on the coast.

Not Panama City or even Destin like that track possibly projects to.

Nope, everyone at this forum knows. Katrina will visit blam's house.

A hurricane did almost exactly the same thing 13 years ago today. It was named Andrew.

The difference, though, was that Andrew exploded into a Cat 5 before Florida landfall, and then after emerging into the Gulf decided not to hit blam's house but chose instead to hit Dog Gone's house.

"Nope, everyone at this forum knows. Katrina will visit blam's house."

That would be a nice break for you. I'll have to go play with the computer models to see why they're forecasting such a sharp right turn. I'm guessing they're forecasting the ridge that's keeping out from heading up the east coast to withdraw over the next few days.

I just read through the 5 PM discussion on the nhl/noaa site:

This is sort of an ominous statement:

"IT SHOULD BE POINTED OUT THAT WITH SSTS NEAR 31C AND A LOW SHEAR ENVIRONMENT...CONDITIONS ARE FAVORABLE FOR POSSIBLE RAPID INTENSIFICATION TO OCCUR BETWEEN NOW
AND LANDFALL."

WFOR-TV/DT Miami has special live coverage (which is streamed via WMP):
Program Notes: CBS4 News special coverage of Tropical Storm Katrina 5-8pm & 11pm-midnight. The CBS Evening News will not be seen. Late Show With Letterman at midnight. Late Late Show With Ferguson at 1:02am. Entertainment Tonight at 2:02am. The Insider at 2:32am. CBS4 News special coverage continues at 4am.
I'm guessing that coverage will be simulcast (as it usually is for landfalling storms in South Florida) on WTVX-TV West Palm Beach.
