NWR Louisiana Coverage

Heavy Rain in the Southwest; Scattered Thunderstorms Across the Great Plains Through the Mid-Atlantic; Ongoing Heat in the Southern U.S.

Monsoon-like conditions will persist across the Four Corners Region over the next several days. Heavy to excessive rainfall may lead to instances of flash flooding. Strong to severe thunderstorms are possible this afternoon across portions of the Great Plains, Lower Mississippi Valley and Mid-Atlantic. Heat wave continues this week from the Southern Plains through Southeast. Read More >

NWR Coverage

Coverage Map Notes

The coverage statistics and maps are calculated using a computer model and station data assuming ideal conditions. Coverage may be 5 to 10 percent below the computer predicted coverage for the following reasons:

The computer model is sensitive to antenna performance. Antenna performance is a function of local conditions, causing signals to be stronger signal level in some directions than others.
Placement of NWR antennas is dictated by the tower owner, which may result in a less than ideal set up.
The antenna may be affected by nearby structures or bodies of water.
In some special instances, the antenna may have been intentionally adjusted to be "directional" and provide better coverage to a specific area to the detriment of other areas.
Because of variations in local site conditions, the performance of an individual transmitter and antenna may be less than predicted or expected.
Seasonal environmental conditions, such as icing or heavy rain, affect performance of a transmitter station and its various components, particularly those subject to continuous weather exposure.
The coverage maps are shown in a single color format, which relates to an estimated signal level.
