Rain is impacting portions of Southeast Texas and the Upper Texas Coast this morning, but luckily we’re not seeing the absurd rainfall rates we saw over the weekend. Training showers with an isolated thunderstorm have continued to impact portions of Southeast Texas and the Upper Texas Coast east of a Montgomery County to Fort Bend County to Brazoria county line. The heaviest rains have been just inland from the coast with moderate to locally heavy rainfall on Interstate 10 in Houston – becoming heavier eastward into Jefferson County. Rainfall rates have been averaging one-half inch to one and a half inches per hour for several hours. This additional rainfall will not allow for local tributaries or bayous to lower. We’re lucky if they’re holding steady, but some are increasing again. Considering most of them are at record levels, we’re in uncharted territory. Rainfall will continue through the pre-dawn hours, although I’m hoping we might start to see it decrease in intensity by 3-4AM. We’re going to have another day of rain potential, but we should be winding down on Wednesday as Harvey starts to pull northeast. See our Monday evening blog for the discussion on Harvey’s track and timeline.

One excellent resource is the Harris County Flood Control District’s observation website. You can observe rainfall rates at varying time periods and check on the water levels at various points. A Texas-wide resource is the Texas Water Dashboard which you can access at the top of the website.
