A graphic describing the threat for excessive rain capable of causing flooding. At least a marginal risk (threat level 1 of 4) exists across Southeast Texas each day this week, with Wednesday standing out with a slight risk of excessive rain (threat level 2 of 4) for the entire area. Though Wednesday generally shows the highest risk across the area, the time of highest threat may be different for a given spot in the area depending on the day that location sees its heaviest rain.
