Hurricane Isaias prompts warnings along the northern US Gulf Coast

The National Hurricane Center reported maximum sustained winds of 140 km/h for Isaias in its October 9, 00:00 Korea-time advisory, maintaining northern Gulf Coast warnings.

The warnings cover specified coastal areas and forecasts; they do not mean the storm has already made landfall throughout Florida or that damage everywhere is established.

Match the wind figure to the issue time

The reference is advisory 8, issued at 15:00 UTC on October 8: midnight on October 9 in Korea, or 10 a.m. Central Daylight Time on October 8. The official bulletin pairs 85 mph with 140 km/h for maximum sustained winds, distinct from peak gusts. WKMG’s independent report covered an earlier hurricane-development stage at 75 mph. Those figures need to be read with their different issue times.

Which areas have which warnings

The hurricane warning extends from Ocean Springs, Mississippi, to the Bay/Gulf County line in Florida. The storm surge warning extends from the mouth of the Mississippi River to Florida’s Suwannee River, a different geographic range. Alabama’s emergency management agency also issued local guidance on wind and flooding. Residents and travelers should check the warning type for their particular coast and jurisdiction, rather than relying only on a state name.

Risks extend beyond the projected center track

NHC forecast landfall in the northern Gulf Coast warning area late on October 9 or early on October 10 local time. That is a forecast window and track, not an observed landfall. The bulletin addresses damaging winds, seawater pushed inland by storm surge and rainfall flooding. A projected center that passes away from a location does not establish that these other hazards will be absent there.

Follow newer advisories and local instructions

This article records the bulletin issued at midnight October 9 in Korea; later updates can change winds, track and warning boundaries. The actual landfall location, intensity and local damage remain uncertain. People in the area should check the latest NHC advisory alongside local weather-office information and evacuation or access instructions from authorities. The generated illustration is conceptual, not a satellite photograph or an operational forecast map, and should not guide decisions.
