Prepping for a flood (Part 4): The go signal

By The SHTF App Team

Human nature is to “wait and see.” We look out the window, see the rain, and think, “It’s not that bad yet.” This is the most dangerous instinct you possess during a flood.

⚠️ Roads flood before homes do. By the time water is lapping at your doorstep, the escape routes are likely already impassable. If you wait until the danger is obvious, you are already trapped. A “Go Signal” is a pre-decided trigger. It removes emotion from the equation. When the trigger is pulled, you don’t debate, you execute. This guarantees you are driving on dry pavement while others are calling for boat rescues.

The Readiness Audit

If a Flood Warning was issued right now, how long would it take you to leave?

  • 🟢 Green: Your car has a full tank of gas, your “Go-Bags” are by the door, and you have a printed map of high-ground routes.
  • 🟡 Yellow: You have a bag, but you plan to check Twitter and the news to see if it “really gets bad.”
  • 🔴 Red: Your gas tank is empty, and you don’t know where you would go.

If you are Yellow or Red, execute Phase 1 immediately.


Phase 1: The Triggers (When to Move)

Goal: Define the exact moment you leave, so you don’t have to think about it under stress.

1. The Official Watch vs. Warning

  • Flood Watch: Conditions are favorable for flooding. Action: Pack the car. Fuel up. Monitor.
  • Flood Warning: Flooding is imminent or occurring. Action: If you are in a flood zone, GO. Do not finish dinner. Do not shower. Leave.

2. The “Personal Trigger”

Do not rely solely on the government. They may be overwhelmed. Set your own line in the sand.

  • Example: “If the creek at the end of the street breaches its banks, we leave.”
  • Example: “If the rainfall rate exceeds 2 inches per hour, we evacuate.”

3. The “Pre-Evacuation” (Beat the Traffic)

  • The Strategy: If you have children, elderly family, or large pets/livestock, you cannot evacuate quickly. You must leave on the Watch, not the Warning.

Phase 2: The 5 Ps of Evacuation (What to Take)

Goal: Rapid packing without forgetting the essentials.

When the adrenaline hits, you will forget your own phone number. Use the 5 Ps mnemonic:

  • P - People & Pets: Account for everyone. Leashes on pets immediately.
  • P - Prescriptions: Meds, glasses, and hearing aids. You can’t buy these easily on the road.
  • P - Papers: Your “Document Pouch” (Insurance, Deeds, IDs) from Part 2.
  • P - Personal Needs: Phones, chargers, and a change of clothes.
  • P - Priceless Items: Photos, heirlooms, or hard drives. Only if time permits.

Phase 3: The Route (Navigation Strategy)

Goal: Avoid the water trap.

1. The High Ground Map

  • The Problem: Your normal route to work/school likely takes the path of least resistance, which is often low-lying.
  • The Fix: Map a route based on elevation, not speed. Avoid underpasses, dips in the road, and bridges over small creeks.

2. The “Turn Around” Physics

  • The Stat: It takes only 12 inches of moving water to float a small car. It takes 2 feet to sweep away a truck.
  • The Invisible Trap: You cannot see if the road under the water is still there. The asphalt may have washed away, leaving a sinkhole.
  • The Rule: If you see water crossing the road, Turn Around, Don’t Drown. Never guess the depth.

3. The GPS Trap

  • Warning: Waze and Google Maps prioritize speed. They may route you onto a “shortcut” backroad that is currently underwater.
  • Action: Trust your eyes and local signage over your app.

Phase 4: Pet & Livestock Protocol

Goal: No one gets left behind.

  • Small Pets: If you evacuate, they go with you. Have carriers ready.
  • Large Animals: If you cannot move horses/livestock, do not lock them in a barn. A barn is a trap. Turn them out into the highest pasture available. They have better instincts than you do and can swim if not trapped in a stall.
  • The Last Resort: If you are rescued by boat/helicopter and they refuse your pet (common), leave the pet loose in an upstairs room with dry food and water, and an open window. Never tether/crate an animal in a flood zone.

The “Essential Kit” Checklist

  • The Full Tank: Keep your car gas tank above half-full during rainy seasons (pumps don’t work without electricity).
  • The Cash: ATMs will be down. Keep $200 in small bills in your Go-Bag.
  • The Analog Map: A physical road map with your “High Ground” route highlighted.
  • The Window Breaker: A glass-breaking tool kept in the center console of your car (in case you drive into deep water).

The Scenario Planner (Contingencies)

Murphy’s Law Variation 1: “I waited too long, and the street is flooded. I’m trapped.”

  • The Trap: Attempting to drive through deep water to escape.
  • The Fix: Vertical Evacuation. Do not drive. Retreat to the highest level of your home.
  • ⚠️ CRITICAL: Do not climb into a closed attic unless you have an axe or saw. If the water keeps rising, you will drown against the roof. Go to the roof itself if necessary.

Murphy’s Law Variation 2: “We got separated in the chaos.”

  • The Trap: Cell towers are overloaded or down.
  • The Fix: The Out-of-Area Contact. Designate one family member who lives in a different state as your “Check-In Point.” Everyone calls/texts them to report safety.
