A system of low atmospheric pressure brewing near Mexico’s Yucatan Peninsula is all but certain to become a tropical cyclone in the Gulf of Mexico over the next 48 hours — but neither Houston nor any part of the Texas Gulf Coast is expected to be landfall target for any developing storm.

The storm system — now called Potential Tropical Cyclone Nine — is most likely to make landfall along the Florida Panhandle.

Tropical Storm Francine is expected to become a hurricane Tuesday and make landfall Wednesday. See radar, path, Texas impact.
