Harvey is expected to restrengthen in southern Gulf

NOAA’s GOES-East satellite provided a visible-light image of the remnants of Tropical Storm Harvey in the western Caribbean Sea on August 21 at 8:30 a.m. EDT (1230 UTC).

They give it a 70% chance of developing over the next two days and a 90% chance in five days.

Thankfully, that hasn’t happened due to strong wind shear and dry air which has helped to keep the area under control as of yet.

This animation shows Harvey negotiating Mexico’s Yucatan Peninsula on Tuesday, Aug. 22, 2017. Tropical weather could increase those chances, however.

What was once Tropical Storm Harvey, which is now a non-tropical system over the Yucatan of Mexico, looks to re-emerge in the Gulf and strengthen into a tropical system again.

Harvey could restrengthen as it makes landfall near the Yucatán Peninsula in the next couple of days.

Winds will be east to northeast at 10 to 15 knots. This amount of rainfall could cause major flash flood concerns, so it’s important to stay vigilant and ready to take precautionary measures.

Among the biggest uncertainties is the heavy rain potential in central Texas, including for the flood-prone cities of Austin and San Antonio.

How far inland drenching rain spreads will depend on how quickly Harvey weakens on the path of the system. Significant flood event possible across the northwest Gulf Coast from Texas to Louisiana late this week through the beginning of next week.

Rainfall totals from Friday through Sunday may be between 4 and 7 inches along much of the Gulf Coast.

“It’s too soon to tell with certainty who gets the worst, but it’s time for us to be weather aware”. NOAA also has excellent resources to plan for flooding.
