Tropical Storm Lee and Our Forecast

Posted: Updated:

We're closely watching Tropical Storm Lee, which is stalled in the northern Gulf of Mexico. Lee became better organized on Friday afternoon, however, some wind shear over the system will likely keep the storm from becoming a hurricane.

Regardless, light winds aloft will keep Lee in place in the northern Gulf near the Louisiana coast 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 pump in rich tropical 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 south of I-20 should be prepared to move to higher ground in the event of flooding. If you live near an area the 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.

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

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.
