Wesley's Blog: Heavy rain brings flood threat

SOUTH MISSISSIPPI (WLOX) - All throughout the month of October, we've been under a drought. So, we need rain. We just don't need too much at one time. And that's exactly what could happen on Sunday into Monday for much of the South.

A non-tropical low pressure system located near the Texas coast on Sunday morning, along with an upper trough of low pressure, is the culprit for our rather wet weather pattern over the next few days (there is no chance for any type of tropical development with the non-tropical low pressure system). It will lead to a flood threat for all of South Mississippi as it treks to the east over the next few days. And the flood threat is two-fold for some.

In addition to regular flooding from rainfall, Harrison, Hancock, & Jackson counties, will have the potential for coastal flooding due to strong onshore flow around the low pressure system. This will cause above normal tides during Sunday evening's high tide.

Any severe weather threat is minimal at best. Though we could hear a few occasional rumbles of thunder, the main threat will likely be heavy rains potentially causing flooding issues.

Heading into Sunday afternoon, widespread rain has spread over much of South Mississippi. But, the steady heavy rain is not expected until later Sunday evening.

Models suggest the heaviest rain should take place Sunday night into Monday morning, with 4"-7"+ rainfall expected in our area by Monday afternoon. Use extreme caution if you plan to travel on Sunday night or early Monday morning. NEVER drive through flooded roadways. Remember: "turn around, don't drown."

Showers will become less frequent by Monday evening. And we could see some more showers on Tuesday on the backside of this system. By Wednesday, the system should be to our east and we may dry out.

As the month wraps up, another rain system looks to move into the area just in time for Halloween. Sure, the timing could hinder Halloween activities. But, keep in mind that it's much needed rainfall that will hopefully bring the South out of this drought that has plagued us for several weeks.
