- Widespread thunderstorms will develop across the area this

boundary and abundant moisture providing favorable conditions
for heavy rainfall. The flood threat will be further
exacerbated by well-saturated soils still present across
portions of the region due to significant antecedent
rainfall. In general, 3-6" of new rainfall can be expected
for areas north of the I-10 corridor through this evening.
Isolated locally higher totals are possible as well. This may
result in street flooding, as well as rises along area rivers
and creeks.
