The BP oil gusher, barring some miraculous, untested solution, will not be stopped for another 3-5 months.
That takes us into August, and maybe September. By then the oil slick will, naturally, have grown substantially.
The early forecast suggests a heavier-than-usual hurricane season.
So what would a direct strike of, say, a category 4 or 5 hurricane , along with its storm surge (oil surge?) mean for the Gulf coast? This is not a rhetorical question. I have no idea whether an oil slick fed by 3-5 months of a 70,000 barrel a day gusher, by itself, is already the worst case scenario, or whether things could get substantially worse.
UPDATE: Yes, it could get worse, and no, nobody knows exactly how bad it would be.
