Weather Warning

Variable afternoon rainfall during this Monday

March 13, 2022

10.40 a.m.

Diagnosis: The high moisture contents that approach the country from the south of the continent, added to weak trade winds due to low atmospheric pressure values in southern Central America, favor episodes of coastal morning rain and periods of continental afternoon rain.

During the early morning and early morning hours of this Monday, very punctual amounts of coastal rainfall between 50-80 mm have been recorded, specifically in Puerto Jiménez and mountains of the Central Pacific.

Forecast: Scattered downpours are forecast for the afternoon period, which may be accompanied by an isolated electrical storm, in mountainous sectors of the South Pacific, Central Pacific and surroundings of Golfo Dulce. The estimated amounts will be between 25 - 60 mm in periods of 12 hours. Isolated downpours accompanied by a storm are likely for the North Pacific in the lower parts of the Tempisque Valley and in the east-southeast of the region. The estimated amounts will be between 30 - 80 mm in periods of 12 hours.

The Central Valley will present variable rains in the afternoon and towards the early hours of the night. The estimated amounts will be between 15 – 45 mm.

The Caribbean regions are estimated to have dispersed clouds, with isolated rains to the west, while the Northern Zone will present occasional downpours towards the early hours of the night. The estimated cumulatives for both regions will be between 10-70 mm.

Warning: The soils with the highest saturation and with the possibility of presenting slight incidents due to rain are the mountainous regions of the Central Pacific and South Pacific, as well as the lower parts of the Golfo Dulce.

Due to the above, the IMN recommends:

• Caution for sewer saturation and possible flash floods.

• Prevention before electrical storm and seek refuge in a safe place in case of appearing or perceiving strong gusts of wind near the storm clouds, due to the possible fall of tree branches, power lines, among others.
