Weather Warning
Tropical Wave #1 over Central America this Saturday
May 23, 2020
10.30 a.m.
Diagnosis: This Saturday, tropical wave # 1 is crossing Central America, reinforcing in its path the atmospheric instability over Costa Rica generated by the Intertropical Convergence Zone. Due to the above, an afternoon and part of the rainy night are expected in much of the national territory.
Forecast: Moderate rains and showers with a thunderstorm are forecast for this afternoon in the Central Valley and mountainous sectors of the Northern Zone and the Caribbean. In addition, rains of variable intensity with electrical storms throughout the regions of the Pacific Slope, being the most intense around the Tempisque Valley (North Pacific) and the Coto Brus Valley (South Pacific).
In the hours of the night, the scattered rains in the national territory, but concentrating them in the mountainous sectors of the country.
Due to the above, the IMN recommends:
• Caution in areas vulnerable to flooding due to sewer saturation.
• Take refuge in a safe place in case of hearing an electrical storm or perceiving strong gusts of wind near the storm clouds, as well as precaution for possible fall of tree branches, power lines, among others.
