Orange : alerte importante, soyez prêt. Rouge : alerte extrême, agissez et suivez les instructions officielles. Des avertissements jaunes (attention) sont publiés par National Weather Service sur son site web.

Y a-t-il un ouragan près de États-Unis ?

Vance : actif, niveau GDACS vert (faible impact prévu). Zone prévue : México.

Que faire en cas de tremblement de terre à États-Unis

  1. Mettez-vous à genoux, abritez-vous sous une table solide et tenez-vous jusqu'à la fin des secousses.
  2. Ne sortez pas pendant les secousses. Restez loin des fenêtres, des façades d'immeubles et des objets susceptibles de tomber.
  3. Si vous vous trouvez sur la côte et que les secousses sont fortes ou prolongées, réfugiez-vous sur les hauteurs sans attendre d'alerte au tsunami.
  4. Quand les secousses s'arrêtent, suivez les instructions des autorités locales et prévenez votre famille que vous allez bien.

Que faire en cas d'alerte de pluie, de vent ou d'orage

  1. Consultez les alertes avant de sortir et modifiez vos plans si le niveau est orange ou rouge.
  2. Ne traversez pas les rues ou les routes inondées, que ce soit à pied ou en voiture.
  3. Évitez les rivières, les ravins et le front de mer lorsque les vagues sont fortes.
  4. Gardez votre téléphone chargé et vérifiez auprès de votre compagnie aérienne ou de votre hébergement pour tout changement.

Que faire en cas d'approche d'un cyclone tropical ?

  1. Suivez la trajectoire prévue du cyclone dans les avis officiels : elle peut changer en quelques heures.
  2. Si les autorités ordonnent une évacuation, partez immédiatement et suivez les itinéraires indiqués.
  3. Gardez à portée de main de l'eau, de la nourriture, une lampe torche, une batterie externe et vos documents.
  4. Vérifiez vos vols : les aéroports ferment souvent pendant le passage d’un cyclone.

Numéro d'urgence en États-Unis : 911

Vais-je recevoir des alertes d'urgence sur mon téléphone en États-Unis ?

À quelle fréquence cette page est-elle mise à jour ?

Toutes les heures, et immédiatement en cas de séisme important, d'alerte rouge ou d'alerte au tsunami. Ces données proviennent d'organismes officiels.
