The storm's water outlives its wind — Polo's remnants fade over Mexico while its moisture overtops a dam on the Rio Grande.

WHAT THEY'RE SAYING

The fading remnants of Polo, drifting out of north-western Mexico toward the border area near El Paso, carry a serious risk of severe flash flooding across the Southwest and High Plains. One weather explainer also points to the chance that these remnants could trigger tornadoes in southeastern New Mexico and western Texas. These details highlight the continued hazards from the system even in its weakened state.
