El Niño Strengthens: Drivers Warned of Slippery Roads During First Rain
IN · Published Oct 21, 2026
• Mercury Insurance has issued a warning to drivers about the dangers of slippery roads as the first rains of the season arrive, coinciding with a strengthening El Niño weather pattern. The National Oceanic and Atmospheric Administration (NOAA) reports an 83% chance of strong-to-very-strong El Niño conditions persisting through early
• The first rainfall after extended dry periods can mix with accumulated oil, grease, and other residues on roads, creating hazardous driving conditions. Drivers are advised to prepare for reduced traction, longer stopping distances, and potential visibility issues. The warning also highlights the importance of vehicle maintenance, such as checking tire tread, windshield wipers, and headlights, to ensure safety during wet weather.

Impact & Risks

The first rain after a dry spell poses significant risks to drivers, including reduced road traction, increased stopping distances, and heightened chances of hydroplaning. These conditions are particularly dangerous at intersections, curves, and heavily trafficked roads. Additionally, standing water on roads can conceal damage, increase hydroplaning risks, or leave vehicles stranded. The strengthening El Niño pattern raises concerns about a wetter winter, which could lead to localised flooding, debris on roads, and changing driving conditions during successive storms. Motorists are urged to remain vigilant and adapt their driving habits to mitigate these risks.
