These are the rainfall amounts forecast to 6am.
The ground is completely saturated. Major flooding will likely develop in the areas that receive 4 inches or more.
Farther south, flood producing rains will likely develop in Texas tonight and Sunday.
Please take this seriously: Do not try to cross flooded areas by foot or by car. That is the leading cause of flooding deaths. If fact, I would recommend curtaining travel after dark in the red area unless absolutely necessary.
If you live in a flood-prone area, please be prepared to move to higher ground at the first sign of rising water.
