Cristobal is expected to make landfall into southern Mexico in the next 24 hours, NWS Houston/Galveston reports this morning. The storm is expected to weaken, then move north toward the central Gulf on Friday.

The latest track shows Cristobal moving toward the central Gulf Coast late Sunday into Monday, but forecasters warn that the future track and intensity of the storm is still very uncertain.

Clouds will increase across Houston Wednesday, with a chance of showers and thunderstorms in some areas. High temperatures are expected in the upper 80s and lower 90s. "Any activity that does develop should dissipate by around sunset and not much development is expected tonight."

Even warmer temperatures are expected Thursday, Friday and Saturday. Daytime highs could be in the mid-90s, with heat index near triple digits, the NWS states.
