About 285 miles west of Progreso Mexico. About 580 miles southwest of the Mouth of the Mississippi River.
Watches and warnings
There are no coastal watches or warnings in effect.
Interests in the Yucatan Peninsula of Mexico and the U.S. northern Gulf Coast should closely monitor the progress of this system.
Hurricane Watches will likely be required for a portion of the U.S. northern Gulf coast later today.
Hazards to land
RAINFALL: Isaias is expected to produce rainfall amounts of 2 to 4 inches through Thursday across coastal portions of the Bay of Campeche with isolated higher amounts possible in the states of Campeche and western Yucatan.
From Friday through the weekend, Isaias is expected to produce rainfall amounts of 3 to 6 inches, with localized totals up to 10 inches, across the northern U.S. Gulf Coast extending from far southeastern Louisiana to the Florida Panhandle. Rainfall amounts of 1 to 3 inches, with localized amounts up to 5 inches, are possible across much of the Southeast as far north as the Tennessee Valley and the Carolinas. Flash and urban flooding, along with isolated river flooding, will be possible.
WIND: Gusty winds are possible in portions of the Yucatan Peninsula on Thursday.
SURF: Swells are expected to affect the western and northern portions of the Yucatan Peninsula beginning on Thursday and spread northward toward the Gulf Coast late this week. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
