256. Lluvia engelante
La lluvia engelante se produce cuando gotas de lluvia subenfriadas se congelan al entrar en contacto con carreteras, vehículos y otras superficies frías, creando una fina capa de hielo. Esto puede hacer que la carretera sea extremadamente resbaladiza aunque parezca simplemente mojada. El conductor debe reducir la velocidad, aumentar la distancia de seguimiento y evitar aceleraciones, giros o frenadas bruscas. Puentes, zonas sombrías y carreteras sin tratar pueden volverse especialmente peligrosos, y las condiciones pueden cambiar rápidamente mientras continúa la lluvia engelante.
What is freezing rain?
Freezing rain is rain that freezes when it reaches a sufficiently cold surface, forming a layer of ice on roads, vehicles and other objects.
Why is freezing rain dangerous for drivers?
Freezing rain can create very slippery and difficult-to-see ice, greatly reducing tyre grip and making steering and braking more difficult.
Is freezing rain the same as snow?
No. Snow falls as frozen crystals, while freezing rain falls as liquid droplets that freeze when they reach a cold surface.
Can freezing rain cause black ice?
Yes. Freezing rain can create a thin, transparent layer of ice that is difficult to distinguish from a wet road and is often described as black ice.
How should you drive in freezing rain?
Reduce speed, increase your following distance and use smooth acceleration, steering and braking. Avoid unnecessary driving if conditions become extremely slippery.
Where is freezing rain most dangerous?
Extra caution is needed on bridges, exposed roads, shaded areas and untreated surfaces, where ice may form quickly or remain longer.
