Heavy rain, strong wind, lightning, hail, and falling branches can damage a pool area in a matter of minutes. In Lansing, MI, storm preparation is especially useful during spring and summer thunderstorms, periods of heavy rainfall, and the transition into winter when freezing conditions can follow wet weather.
Protecting a pool does not mean draining it completely or covering every component without a plan. The goal is to reduce flying debris, prevent equipment damage, control water levels, and keep electrical and structural hazards from developing.
What should be done before a storm reaches the area?
The most useful preparation happens before severe weather arrives. Remove loose objects from around the pool, check the drainage path, and confirm that equipment is protected from flooding and wind-driven debris.
Walk the pool area and secure or store items such as:
- Patio furniture and umbrellas
- Toys, floats, and cleaning tools
- Lightweight planters and decorations
- Pool covers that are not designed for high winds
- Loose branches or yard debris
- Temporary fencing or freestanding equipment
Objects that seem harmless can become projectiles during strong wind. Even a plastic chair can damage a pool liner, fence, screen enclosure, window, or outdoor equipment.
Trimmed trees also deserve attention. Branches that hang over the pool, pump, filter, or electrical equipment may break during saturated-soil conditions or gusty weather. Do not climb trees or cut large limbs near power lines. Those conditions require appropriate safety precautions and, when necessary, qualified assistance.
Should the pool be covered during a storm?
A properly installed cover can reduce leaves, branches, and sediment entering the water, but not every cover should remain in place during severe weather. Lightweight solar covers and floating thermal covers are not intended to restrain large debris or withstand strong wind. They may tear, blow away, or become difficult to remove.
A safety cover should be secured according to its installation design. Avoid placing heavy objects on it because they can damage the cover or create a hazard around the pool. Do not walk on a cover unless it is specifically rated and installed for that purpose.
If the cover is already loose, damaged, or partially detached, trying to fasten it during high winds can be dangerous. Secure the area from a safe location and wait until conditions improve before making adjustments.
An uncovered pool is not automatically unprotected. In some storms, a loose cover can cause more damage than temporarily leaving the water exposed, particularly if wind can get underneath it.
How should pool equipment be protected from flooding?
Pool pumps, filters, heaters, timers, and electrical connections can be damaged by standing water. Before a major storm, inspect the ground around the equipment pad and identify whether runoff could collect there.
Useful precautions include:
- Clear leaves and sediment from nearby drains and grading paths.
- Keep equipment doors and access panels closed.
- Move portable electrical devices away from low areas.
- Shut off power to pool equipment if flooding is likely, following the equipment instructions.
- Do not touch electrical equipment while standing in water.
- Never operate a flooded pump, heater, outlet, or control panel until it has been inspected and confirmed safe.
Do not place plastic sheeting directly over operating equipment without allowing proper ventilation. Trapping heat or moisture can create another problem. Equipment protection should prevent direct exposure to water without blocking required airflow or access.
If water has reached electrical components, the safest approach is to keep people away from the area and have the electrical system evaluated before power is restored.
Should the pool water level be lowered before heavy rain?
Usually, the water level should not be lowered significantly before a storm. An in-ground pool depends on the weight of the water to counteract pressure from surrounding soil. Draining too much water can increase the risk of structural movement, especially when the ground is saturated.
A small adjustment may be appropriate if the pool is already unusually full and the overflow system is not working properly. However, removing large amounts of water can create greater risks than allowing rainwater to enter the pool.
Above-ground pools require different considerations. Excess water can place added stress on the wall, liner, supports, and surrounding ground. Keep the pool filled to the manufacturer’s recommended level unless specific instructions call for another approach. Do not drain an above-ground pool simply because heavy rain is forecast.
After the storm, remove excess water using the pool’s normal drainage or circulation system. Avoid directing discharge toward the foundation, neighboring property, septic area, or a slope where erosion could occur.
What should be done with the pool pump during lightning?
Lightning creates a serious electrical hazard around pools. People should leave the water and surrounding deck immediately when thunder is heard, not wait for visible lightning.
Pool equipment should be operated according to its instructions, but storm safety takes priority. If the electrical system can be safely switched off before the storm arrives, that may reduce the chance of equipment damage. Never walk through standing water to reach a disconnect, and never handle plugs, switches, or equipment with wet hands.
Keep everyone away from the pool until the storm has passed and there has been a reasonable period without thunder. A pool can remain electrically hazardous even when rainfall has become light.
How can landscaping reduce storm damage?
Pool protection begins beyond the pool deck. Yard drainage, planting locations, and tree maintenance all influence how much water and debris reach the pool.
In Lansing, seasonal rain can saturate soil quickly, particularly where compacted ground, poor grading, or heavy clay soil slows drainage. Check whether water flows toward the pool, equipment pad, retaining wall, or house foundation. Keep soil, mulch, and decorative stone from blocking drains or covering skimmer lids.
Planting beds near the pool should be inspected for erosion after heavy rain. Washed-out soil can expose roots, shift edging, and carry dirt into the water. Replacing damaged soil and redirecting runoff after the ground has dried can prevent repeated problems.
Avoid stacking firewood, bags of soil, garden tools, or construction materials near the pool. These items can shift during wind or become saturated and unstable.
What should be checked after the storm?
Wait until lightning, high winds, and standing water have cleared before inspecting the pool. Begin from outside the pool area and look for hazards before turning on equipment.
Check for:
- Downed wires or damaged electrical components
- Broken branches and unstable trees
- Fence, gate, deck, or railing damage
- Tears, gaps, or displacement in the cover
- Cracks in the pool shell or deck
- Loose coping, damaged liners, or shifted above-ground supports
- Excessive debris or cloudy, discolored water
- Soil erosion near the pool and equipment pad
Do not enter the water if electrical damage is suspected. Do not restart equipment that is submerged, making unusual noises, or showing signs of impact.
Once the area is safe, remove large debris with a net rather than allowing it to sink. Check the water level, empty baskets, inspect the filter pressure, and test the water chemistry. Stormwater can dilute chemicals, introduce organic matter, and alter pH and sanitizer levels.
If the pool has a salt system, heater, automated controller, or other specialized equipment, follow the manufacturer’s storm and restart instructions. Documenting damage with photographs can also help with household records or insurance questions.
Preparing loose items, protecting electrical equipment, maintaining drainage, and avoiding unnecessary draining are the most reliable steps for reducing storm-related pool damage. These measures also make post-storm cleanup safer for area households.
