Storm Polo weakens over Mexico as Rachel gathers strength offshore

Forecasters said moisture from Polo and Odalys could bring 2 to 3 inches of rain in parts of Arizona and trigger flash flooding.

  • On Wednesday, Sept. 30, 2026, remnants of Hurricane Polo combined with an upper-level system to trigger heavy rainfall across North Texas, producing significant accumulation through the end of the week.
  • Tropical moisture from Hurricane Polo is being funneled inland by a sprawling upper-air trough, creating a hybrid system with an incoming non-tropical storm that heightens downpour risks across the Southern Plains.
  • Governor Greg Abbott announced the state mobilized more than 1,900 first responders and 1,500 pieces of equipment, while meteorologists forecast 1-4 inches of rainfall with isolated totals near 8 inches.
  • A flood watch remains in effect for Dallas from Wednesday afternoon through Thursday, as rain chances climb to 100 percent and officials warn driving around barriers can result in fines up to $2,000.
  • Overlapping rounds of rain could significantly increase flash flooding potential in saturated areas as the slow-moving system lingers through Friday, particularly where heavy rain falls repeatedly.
