NEW ORLEANS — Isaac is now a Category 1 Hurricane with 75 mph winds.
Some drier air working into the storm has slowed down the strengthening process. Also, since Isaac is moving over cooler and more shallow waters in the northern Gulf, the storm may not have much time left to strengthen too much.
The biggest threat with this storm will be flooding not winds. The storm surge may be between 6-12 feet right along the coast.
Plus, flooding rains of over a foot are possible not just along the coastline but further inland. Isaac's remnants will move northward into the midwest and are not expected to arrive in the Carolinas.
