That is Lake Pontchartrain on the north. A hurricane spins counterclockwise. If the hurricane is to the west, it will push the lake water toward the upper left corner of the map, away from New Orleans. If the hurricane is to the east, it will push the lake water toward the lower right corner, right over New Orleans.
The meterologist on Fox said it could shift slightly east before landfall.
but how far west would it have to hit to lessen the effects? Bastardi saying his prediction is 30 miles east of New Orleans for landfall. So if the choice is 30 miles to the east with 100MPH winds with the flooding from the lake, or a dead on hit, which is better?
