Houston appears to be outside the forecast cone of the tropical disturbance in the Gulf of Mexico, according to the National Weather Service, but that doesn’t mean it’s clear skies ahead.

There’s a 40 percent chance of showers and thunderstorms Thursday, mainly after 11 a.m. The high is expected to reach 97 with heat index values as high as 103.

The chance of rain drops to 30 percent Thursday night with a low around 80.

There’s a lingering possibility of rain in the forecast for Friday: 30 percent chance of showers and thunderstorms in the afternoon. The high will be near 95.

While the storm is not likely to hit Houston, meteorologists predict it could develop into a hurricane before making landfall in Louisiana this weekend.

New Orleans this morning is still under a flash-flood warning, which is expected to extend to Sunday.

The National Hurricane Center warns that the biggest threat this storm poses is continual rain: “The slow movement of this system will result in a long duration heavy rainfall threat along the central Gulf Coast and inland through the lower Mississippi Valley through the weekend and potentially into next week.”

There’s a possibility that the flooded Mississippi River could be lapping at the tops of levees this weekend.

Wednesday morning flooding affected downtown New Orleans. Residents could be seen kayaking in the streets as the storm stopped rush-hour traffic in that city.
