It’s starting to rain and, more often than not, the rainfall comes as a surprise.

The folks here at work asked me for some weather-related advice for older car owners or even for EV and HEV newbies.

So, as we are beginning to experience increasingly intense rainfall, flash floods and on other days prolonged periods of extreme heat, car owners face evolving climate‑related risks.

From flooded roads and low‑lying car parks to high temperatures that may affect vehicle performance, local driving conditions require greater awareness and preparedness.

So yes, got some advice for you, young and not-so-young folks, who have invested in an EV, an HEV, or have to drive the old and shaky family car, and have to face the rest of the year’s rain, storms and floods.

Drive less during heavy rain and bad (bed) weather

During periods of heavy rain or stormy weather, reducing your time on the road can significantly lower your exposure to accidents and environmental hazards. Wet surfaces, reduced visibility, flash floods and falling debris all increase driving risks. Where possible, consider delaying non‑essential journeys or using public transport.

If you’re part of the off-peak driver — there’s even more to gain. Driving during off‑peak hours can keep you away from traffic build-up, which is a good thing.

Park on higher ground (That means no matter where you go)

Flooding can occur rapidly in low‑lying areas, car parks and lower roads during intense rainfall. Whenever possible, park your vehicle on higher ground, especially during monsoon seasons or when heavy rain advisories are issued. Avoid parking: along roads or areas known to flood; near drains, canals, or bodies of water; under trees, power lines, or unsecured structures during storms.

These simple precautions can help reduce the risk of water ingress, falling debris, or secondary damage.

Avoid driving through flooded roads

Even shallow floodwaters can be dangerous. As little as 30 centimeters of moving water can cause vehicles to lose traction or be swept away. If you encounter a flooded road: Do not drive through if the water depth is unclear; wait for floodwaters to subside or seek an alternative route; if water levels rise rapidly, exit the vehicle and move to higher ground when it is safe to do so.

For electric vehicles, flood exposure may affect electrical and electronic components, even if the vehicle appears to function normally afterwards.

Check weather and traffic updates before driving

Before setting off during periods of heavy rain or storms, check weather forecasts and traffic conditions. Navigation applications such as Google Maps or Waze can help identify flooded roads, congestion hotspots, and road closures in real time. Planning ahead allows drivers to: Avoid high‑risk routes; delay travel during severe weather; choose safer alternative routes.

These steps help reduce unnecessary exposure to weather‑related risks.

For EV owners, protect your vehicle from heat and extreme temperatures.

The Philippines tropical climate means consistently high temperatures throughout the year. Prolonged exposure to heat can affect vehicle interiors, onboard electronic and EV battery systems. To reduce heat‑related impact: Park in shaded areas whenever possible; Use sunshades to lower cabin temperatures; Avoid leaving your vehicle in direct sunlight for extended periods.

Managing heat exposure supports overall vehicle performance and helps preserve battery efficiency over time.

Avoid frequent fast charging during hot weather

Fast charging generates additional heat, which combined with high ambient temperatures may accelerate battery wear if done frequently. When possible: Use slower AC charging, especially overnight; I have been told that it might not be good to always use a “fast charger.” Better to avoid repeated fast‑charging more so during very hot days. Allow the battery to cool between charging sessions. These practices help support long‑term battery health and make for more efficient EV ownership.

Keep your EV well‑maintained

Regular vehicle maintenance is one of the most effective ways to reduce weather‑related risks. Important checks include: Ensuring tires have sufficient tread for safe driving on wet roads; Inspecting brakes and suspension for proper handling; Making sure doors, windows, and seals are intact and securely closed.

If your vehicle has been exposed to flooding, it should be inspected by a qualified shop as soon as possible to detect potential electrical or mechanical issues.

Follow local safety advisories

Pay attention to advisories issued by local authorities such as Metropolitan Manila Development Authority, the Land Transportation Office and the schools and barangay and village association. These alerts provide timely information on flood‑prone areas, road conditions, and recommended safety actions that can help drivers make informed decisions.

If you use a portable EV charger, make sure to use approved EV charging equipment. More so if it is raining. If you plan to load up in a charging station, be ready for long waits. Bring a book or eat a snack while waiting.

Always use manufacturer‑approved or certified charging equipment at home and at public charging stations. Damaged or non‑certified accessories may increase electrical risks, especially during wet weather. Avoid charging your EV if: Charging cables or connectors appear damaged; there is standing water near the charging point or if the charging area is unsheltered during heavy rain.

Hope this helps. Until the next detour!
