The primary risk for the Houston area is localized flooding, particularly in areas prone to poor drainage. Monday's rainfall caused minor inconveniences, but the potential for heavier rain midweek could escalate the situation. If the forecasted 20-inch rainfall bullseyes materialize, significant flooding could occur, especially in low-lying areas. However, there is still uncertainty in the forecast, and the heaviest rain may miss the Houston metro area entirely. Residents should remain vigilant and monitor updates, as conditions could change rapidly.
