Gulf system strengthens Zee forecasts landfall risk

Oct 6

David Muir and Ginger Zee track a strengthening system in the southwestern Gulf that Zee expects to become Isaias. She forecasts eastward then northward movement and possible hurricane landfall Friday night into Saturday, urging attention from Louisiana through coastal Mississippi and Alabama to the Florida Panhandle. She explains that the cone represents possible center locations and impacts can extend outside it. Warm Gulf water could fuel development, while upper-atmosphere conditions could impede it. Her forecast includes more than half a foot of rain in some outer bands, possible west-Florida effects, surge and tornadoes. Formation, hurricane intensity and landfall are forecasts rather than completed occurrences.

On October 6, ABC tracks a strengthening tropical system in the southwestern Gulf. Ginger Zee expects it to become Isaias and forecasts eastward then northward movement and possible hurricane landfall Friday night into Saturday along the northern Gulf coast. She urges attention from Louisiana to the Florida Panhandle, explains impacts may extend outside the center-track cone, and forecasts heavy rain, surge and tornado risks despite potentially inhibiting upper-atmosphere conditions. Naming, hurricane intensity and landfall remain forecasts.
