Threats & Impacts:
Less than 2 inches west of Highway 281, 1-3 inches for the I35 corridor, and 2-4 inches for the Coastal Plains. Isolated locations could receive 5-7 inches (mainly in the Coastal Plains).
Timing and Overview:
While there is a 20% chance for tropical cyclone development, significant strengthening of the tropical disturbance is not expected. This disturbance will bring a chance of decent rainfall to the area beginning in the eastern half today and spreading to most of South-Central Texas Monday-Wednesday. While significant flooding is not expected due to dry antecedent conditions and breaks in activity, minor flooding is possible in areas that pick up the isolated higher totals. The disturbance is expected to exit the region by Wednesday, but if it strengthens/slows down, the rainfall total forecast could increase slightly.
