Hot and muggy weather will dominate the area for the first few days of the week. A heat advisory will be in effect for all of Acadiana. Humidity levels continue to be quite high, and heat index values will approach 110 degrees again today. Several across the western parishes are still without power due to Hurricane Laura's landfall last week, so the weather misery level will be about as high as it can get. Therefore, the criteria for a "Heat Advisory" has been lowered to heat index values over 100 rather than the normal 108. This will be in effect for parishes that have at least 10% of customers without power. Once power is restored, those levels for a heat advisory will return to 108.

There is still enough moisture in place to spark off scattered showers and thunderstorms. Most of these will occur during the afternoon. Temperatures will start in the upper 70s and lower 80s, with highs in the low 90s this afternoon. Winds will be light out of the southwest.

Over the next several days, high pressure will be building in. This should shut down some of the afternoon rain chances. Humidity levels will remain high, so heat index values will remain between 105 and 110.

Tropical weather remains quiet close to home. There's an area of disturbed weather near the Carolina coast that will pull into the Atlantic, with no threat to Acadiana. Another stronger wave is located over the eastern Caribbean has an 80% chance for development over the next five days. This wave is expected to cross the Caribbean and could impact areas of Central America. At this time it appears it will stay south of our region.
