Regardless of whether or not 91L becomes Tropical Storm Bill before it makes landfall, the system will post a distinct threat of serious flooding over a broad swath from eastern Texas into Oklahoma. Both states just experienced the wettest single month in their history, and soils remain near saturation. Even without such a worrisome precondition, systems like 91L are notorious for producing enormous amount of rain, sometimes with tragic results. 91L has a large and very moist circulation, and steering currents will be weak as the system slowly moves around a strong, hot dome of high pressure over the Southeast. Slow-moving systems need not be intense prior to landfall to generate huge rainfalls once they’re inland, as demonstrated by a number of Gulf of Mexico systems during June and July, when upper flow is often listless. Tropical Storm Allison is a textbook example: in June 2001, Allison drifted into east Texas, then circled back southward and made a second landfall in Louisiana, dumping as much to 38” of rain over six days across parts of the Houston area
Tropical Storm Bill continues to trek closer to the mid Texas coast
this morning. Bill is expected to make landfall near Matagorda Bay
between 9 and 11am and track into south-central Texas late this
afternoon into tonight.
Storm total rainfall amounts from starting this afternoon through
Wednesday night will range from 3 to 6 inches along and east of U.S.
281 with isolated amounts up to 8 to 12 inches along and east of an
Georgetown to Cuero line. High impact flash flooding and potential
moderate to major flooding of some rivers and creeks will be
possible late tonight through Wednesday night across portions of
south-central Texas. Residual river and creek flooding could linger
well into next week for highest impacted areas.
