The AP reports (h/t Drudge) that Isaac is headed for New Orleans. However, the storm will not be as severe as Katrina.
The Gulf Coast region has been saturated thanks to a wet summer, and some officials have worried more rain could make it easy for trees and power lines to fall over in the wet ground. Too much water also could flood crops, and wind could topple plants such as corn and cotton.
"A large, slow-moving system is going to pose a lot of problems: winds, flooding, storm surge and even potentially down the road river flooding," said Richard Knabb, director of the National Hurricane Center in Miami. "That could happen for days after the event."
The storm's potential for destruction was not lost on Alabama farmer Bert Driskell, who raises peanuts, cotton, wheat, cattle and sod on several thousand acres near Grand Bay, in Mobile County.
"We don't need a lot of water this close to harvest," Driskell said.
However, Isaac could bring some relief to places farther inland where farmers have struggled with drought. It also may help replenish a Mississippi River that has at times been so low that barge traffic is halted so engineers can scrape the bottom to deepen it.
Forecasters predicted Isaac would intensify into a Category 2 hurricane, with winds of about 100 mph, by early Wednesday around the time it's expected to make landfall. The current forecast track has the storm aimed at New Orleans, but hurricane warnings extended across 280 miles from Morgan City, La., to the Florida-Alabama state line. It could become the first hurricane to hit the Gulf Coast since 2008.
