This Sunday July 13, at 2:33 p.m., the National Weather Service issued a flood advisory for Houston, in effect until 4:30 p.m. The advisory warns of minor flooding in low-lying and poor drainage areas due to excessive rainfall. As always, officials remind drivers: “Turn around, don’t drown.” Most flood-related deaths happen in vehicles attempting to cross flooded roads.

If you’re unsure what all these alerts mean, advisories, watches, warnings, here’s a breakdown to help you stay informed:

What Each Flood Alert Means:

• Flood Advisory (Be aware): Flooding is possible and may cause inconvenience or minor hazards. Use caution, conditions can escalate.
• Flood Watch (Be prepared): Weather conditions are favorable for flooding. No flooding is occurring yet, but it could happen.
• Flood Warning (Take action): Flooding is happening or will happen soon. Move to safety if you’re in a flood-prone area.
• Flash Flood Warning (Take action immediately): Flash floods are sudden and dangerous. Get to higher ground fast, even if it’s not raining where you are.

What To Do Before and During a Flood

The National Weather Service offers key tips to protect yourself and your home when flood risks rise:

• Move to higher ground if you’re in a flood-prone or low-lying area.
• Follow evacuation orders right away and lock up before leaving.
• Disconnect utilities and appliances if time allows to prevent electrical hazards.
• Avoid basements and water-submerged areas with visible outlets or cords.
• Evacuate if you hear electrical sounds like buzzing or popping, don’t risk electrocution.
• Never walk through floodwater. Just 6 inches of fast-moving water can knock you down.
• Call 911 and climb to a higher point if you become trapped by water.
