From the National Hurricane Center:
A HURRICANE WARNING IS IN EFFECT FOR...
* EAST OF MORGAN CITY LOUISIANA TO DESTIN FLORIDA...INCLUDING
METROPOLITAN NEW ORLEANS...LAKE PONTCHARTRAIN...AND LAKE MAUREPAS
MAXIMUM SUSTAINED WINDS ARE NEAR 65 MPH...100 KM/H...WITH HIGHER
SOME STRENGTHENING IS FORECAST AND ISAAC IS EXPECTED TO BECOME A HURRICANE BEFORE REACHING THE NORTHERN GULF COAST.
Both the path and the intensity still have some uncertainty. It currently appears that the city of New Orleans needs to be prepared to be battered by this tropical storm. Landfall could occur early Tuesday evening.
Excessive rainfall is a serious threat as the computer models slow the inland movement of the tropical storm on Tuesday night and Wednesday.
I'm curious how the forecast track will affect the midwest. The cone of uncertainty brings it into the heart of the driest part of the country. Will this make life better for farmers? Also, will the storm push far enough north to affect Minnesota's weather?
There will be some very beneficial rains moving inland with the remains of the hurricane. Some places may get more rain than they wish for in a short time.
Unfortunately, generous rain may not extend to many regions that badly need moisture. Standby
