Condiciones lluviosas vespertinas en el Pacífico y Valle Central
3 de diciembre de 2020
1 p.m.
Diagnóstico: la cercanía de la Zona de Convergencia Intertropical, así como la inestabilidad atmosférica presente son factores que favorecen las precipitaciones vespertinas.
Pronóstico: En la tarde y durante la noche se mantendrán lluvias de variable intensidad en el Península de Nicoya, Pacifico Central y Sur, se estiman montos entre 20-70 mm en períodos de 12 horas. Para el Valle Central y Zona Norte se prevén lluvias intermitentes, con acumulados menores a 10-20 mm. En las regiones del Caribe se tendrán condiciones nubladas sin precipitaciones.
Advertencia: Especial atención en el Pacífico Sur ya que se mantiene alto porcentaje de saturación de suelos.
Debido a lo anterior, el IMN recomienda:
- Precaución en zonas con vulnerabilidad a inundaciones por crecidas de ríos y quebradas, así como en sectores propensos a deslizamientos.
- Prevención por ráfagas de viento y su posible afectación de techos, cableado eléctrico, rótulos, árboles; así como en las partes montañosas del país (parques nacionales, volcanes).
