The hurricane weakened as it tracked farther inland, degenerating into a tropical storm within a day of its landfall in Texas. A northeast curve soon followed, resulting in a track into the Ozarks and Ohio River Valley; the storm transitioned into an extratropical cyclone on August 20 over the Ozarks and dissipated over the Gulf of Saint Lawrence three days later. Heavy rainfall and significant river flooding occurred along the storm's path during this latter phase of its evolution. Levee breaches in along the White River in Arkansas and the Mississippi River in Illinois flooded entire towns. St. Louis, Missouri recorded its rainiest 24-hour period in history, experiencing a deadly flood of the River Des Peres and Meramec River that impacted much of the city and surrounding suburbs, killing 20 people and destroying over a thousand homes.
