Tropical Storm Lee Update

Posted: Updated:

Tropical rain bands from Lee continue to move northward across the area. These rain bands will overspread central Mississippi through the day.

Lee has stalled just off the Louisiana coast. The center is expected to make landfall along the south-central Louisiana coast by tonight.

Light winds aloft will keep Lee in place across southeast Louisiana through the weekend. By late Sunday or Labor Day, a cold front may finally help to pull Lee northeast across south Mississippi, then into Alabama by Tuesday afternoon. 

Until then, the system will continue to pull moisture into central and south Mississippi. I expect numerous bands of heavy tropical rains to move inland through the weekend. It does not get much more tropical than this and, as a result, rainfall rates will be very high.

Due to the slow movement of Lee, these bands of rain will likely move over the same areas, allowing even more water to pile up.

Everyone across central and south Mississippi, especially those in southeast Mississippi, should be prepared to move to higher ground in the event of flooding. If you live near an area that floods, such as a creek, stream, pond, or low-lying area, you need to especially be weather aware through at least Monday.

Rainfall totals through Labor Day could range as high as 5-8" in parts of central Mississippi, with totals near 10"-15" across parts of southeast Mississippi.

In addition to flooding, land-falling tropical systems can produce severe storms, which can spawn isolated quick spin-up tornadoes. These tornadoes are often very weak, normally EFO-EF-1 intensity. Rotation in these storms can be hard to detect on radar, so often times there may be little or no warning. This tornado threat is isolated and mainly confined to south Mississippi.

A Tornado Watch is in effect until 10PM for Amite, Pike, Walthall and Wilkinson Counties.

Keep in mind the track and speed of Lee is subject to change and any significant changes would impact the rainfall forecast and the tornado risk area.

The widespread clouds and rain will hold temperatures down into the 80s and even 70s for highs this weekend. Lows will be in the low to middle 70s.

You can get the latest on Lee by downloading the First Alert Weather app for i-Phone or Android. Also, sign up for free text message weather alerts. I will also be updating Twitter through the day.
