It's back. The heat is on again and the temperatures will soar into the low 90s again today.

The National Weather Service has issued a heat advisory, and that happens when the combination of heat and humidity make it feel like it's 95 to 99 degrees for two or more consecutive days, or 100 to 104 degrees for any length of time.

When you combine the temperature along with the humidity and the dew point, you come up with the heat index, and that's what makes it feel a lot hotter then the actual air temperature. Today, it's actually going to feel like it's close to 100 degrees.

Those who are elderly or have breathing problems are always at risk when the weather turns this hot, so the state Department of Emergency Services and Public Protection requests that anyone who needs a cooling center contact 2-1-1.

Just remember to check on elderly neighbors, stay hydrated, keep your pets in a cool comfortable place, and never leave children or pets in a parked car.

If you work outside, try and schedule rest breaks in shaded or air conditioned area's. If you feel like you have heat stroke, move to a shaded area immediately, and call 9-1-1.
