¿Va a hacer senderismo o a acampar durante el monzón? ¡Consulte el pronóstico primero! ⛺🥾 Los cañones estrechos y arroyos pueden inundarse a causa de tormentas ocurriendo a varias millas de distancia de los mismos. Tenga siempre un plan B. Si escucha el retumbar de los truenos o ve formarse nubes negras, diríjase de inmediato a un lugar seguro. Evite las zonas bajas y los arroyos secos. Respete la Tormenta.

¡Vientos severos pueden azotar incluso antes de que comience a llover!💨 La fuerte corriente descendente de las tormentas monzónicas puede generar vientos superiores a los 80 mph, causando daños materiales. Asegure los muebles de exterior y los objetos sueltos antes de la llegada del monzón. Prepárese para posibles cortes de electricidad y manténgase alejado de las ventanas durante los vientos fuertes.

Look for another dry day before moisture begins to sneak across northern Arizona starting Friday. We will likely only see a few cloud buildups on Friday but over the weekend, look for showers and thunderstorms scattered around northern Arizona. Activity could linger into Monday. The first taste of our coming monsoon, let's hope it's a good one.
