Expecting Isaac to be upgraded to a cane--

Isaac has been the SLOWEST developing storm I've even watched- like paint drying. Giving the NHC full credit, they said it would be a slow process and they were correct. Next update should have it at 75 MPH, maybe 80. It may get close to 100 MPH, but not much more. The official forecast is for it to remain a Cat 1 storm.

Note this image where the convection is finally wrapped around the eye. As this builds, the storm should get stronger.

The bigger problem will end up being rain and flooding. 90-100 MPH winds are dangerous, but they will be confined to the most outlying and coastal areas. There will be widespread power outages, but it should not be total devastation.

NHC preferred track.

Rainfall will be the biggest issue. Strongest winds and rains are always to the center (eye) and east of the system. Note the rain is forecast to be heaviest to the east of the landfall spot. New Orleans gets off with only 8-12 inches of rain while Southern Mississippi gets 15-18 inches.
