July 27, 2020
02.40 p.m.
Discussion The proximity of the Intertropical Convergence Zone, the warm morning temperatures and the entry of sea breezes have generated in the early hours of this afternoon cloudy developments and at the same time heavy downpours with gusts of wind and thunderstorms in the South Pacific, sectors mountainous of the Central Pacific, as well as in the Central Valley with accumulated between 10-25 mm in the last two hours.
Forecast: In the remainder of the afternoon there will be rains of variable intensity, heavy showers with thunderstorms in the Pacific, North Zone, Central Valley regions; accumulated 40-60 mm, higher amounts are possible in a localized way. In the Caribbean, rains are expected in the mountainous sectors with accumulated between 10-30 mm.
The precipitations will extend to the first hours of the night in the Pacific -especially coastal areas-, as well as in the North Zone with amounts between 20-50 mm. In the Central Valley and mountains of the Caribbean, scattered weak rains are possible, accumulated 5-15 mm.
The incursion of tropical wave # 23 is estimated in the early hours of this Tuesday, which can generate a reinforcement in rainy activity, mainly in the afternoon and evening periods. During the morning cloudiness and possible rains are expected in the Caribbean and the North Zone. In the afternoon, heavy rains and showers are expected in the Pacific and Central Valley regions.
Warning: Considerable soil saturation is maintained in sectors of the North and South Pacific, as well as in the North Zone; therefore, special attention is requested.
Due to the above, the IMN recommends:
- Caution in areas vulnerable to flooding due to increased flow in rivers and streams.
- Take refuge in a safe place in case of listening to a thunderstorm or perceiving strong gusts of wind near storm clouds, as well as caution for possible falling tree branches, power lines, among others.
