The remains of a tropical storm were across the eastern Pacific near the southern tip of Baja, California.  Mid-level flow across the area was from the southwest which allowed for tropical moisture to get transported into the region.  Low-level winds were from the southeast which allowed for moisture from the Gulf of Mexico to get advected into the area.  This abundance of moisture was combined with instability and various shortwave troughs that moved over the area to provide lift to help sustain heavy rain over West Texas and Southeast New Mexico.
Places across the Permian Basin and Trans Pecos had reports of flooding and water rescues.  Most of the flooding occurred in the Midland and Odessa areas where the combined damage is estimated to be around three million dollars.  The City of Big Spring also reported significant flooding.
