Houston is the fourth-largest city in the United States and one of the most hurricane-vulnerable major metros in the nation. Sitting just 50 miles from the Gulf Coast at an average elevation of 43 feet, the city faces catastrophic flooding risk from both direct hurricane strikes and tropical rainfall. Hurricane Harvey in 2017 dropped over 60 inches of rain across the metro area — the highest rainfall ever recorded from a tropical cyclone in the continental US — inundating over 300,000 structures and causing $125 billion in damage.

// Preparedness Recommendations

  • Evacuation routes inland should be identified in advance.
  • Store at least 72 hours of food and water.
  • Elevate critical belongings above flood level.
  • Have backup power ready in case of grid failure.

// Recommended Supplies

Essential gear for power outages, severe weather, and emergency situations in your area.
