HOUSTON—Heat indexes in the Houston area will be well above 100 degrees Tuesday and there is an Ozone Watch in effect for sensitive groups.

"Keep in mind elevated levels of ozone can act as a lung irritant so if you are sensitive, it may be a day to stay inside during the afternoon hours," KHOU 11 News Meteorologist Chita Johnson said.  "It peaks between 2 and 7.p.m. and it mainly affects children and the elderly."

Temperatures in areas north of the city will be hotter, topping out at 97 degrees, and the heat index will range from 102 to 107 degrees.

“This is a hot weather precaution day,” said Johnson. “Drink water and take breaks in the air conditioning, give your body a chance to recuperate.”

Rain chances Tuesday are only 30 percent, mainly in the afternoon. And you can expect his hot weather pattern to hang around through the end of the week.

Meanwhile, Tropical Storm Ernesto was headed toward the Yucatan Peninsula Tuesday, where it’s expected to make landfall – possibly as a hurricane – by early Thursday morning.

It will not affect Texas, but there’s another disturbance out in the Atlantic that has a chance to develop into something more.

The new system has a 20-percent chance of development, but it’s too soon to tell what direction it will take.
