Vast majority of the flooding, to my understanding, is North of Houston, in the San Jacinto river basin area. I'm not too familiar with the area, but there are different forks in the river, and one fork is heavily flooding. Either way, we really have not received much rain at all here in Southern Brazoria County where I live. About 50 miles south of Houston proper. North of Houston is a whole 'nother story. They've been getting hammered, almost record floods. Some of the water will make it's way down here, but the Brazos River is the one that affects us here (the mouth of the brazos is in our county).
