Weather Report N°1
Variable precipitation in the Caribbean, the Northern Zone and parts of the Pacific
April 9th, 2024
3:00 p.m.
Diagnosis: The constant entry of humidity from the Caribbean Sea and the unstable atmosphere near Costa Rica due to the proximity of the Intertropical Convergence Zone, has generated variable rainfall in the morning for the Caribbean regions and the Northern Zone, in addition to downpours with storm located in parts of the Pacific slope and Central Valley. For the last 6 hours, there have been records of between 10 - 45 mm in the Northern Zone, between 20 - 50 mm with specific maximums of up to 70 mm (Limón, Cahuita) for the Caribbean regions. As for the regions on the Pacific slope, all have accumulations of less than 25 mm.
The highest wind gusts recorded are present in the mountain ranges and low sectors of the North Pacific, with intensities between 40 km/h and 65 km/h.
Forecast: During the rest of the afternoon, variable rains will continue in the Caribbean regions and the Northern Zone, with estimated amounts in 6 hours between 5 mm and 50 mm. On the other hand, downpours with occasional storms are expected in the mountains - locally in low parts and near the coasts of the Pacific slope - with estimated accumulations in 6 hours of between 20 to 50 mm with specific maximums of up to 70 mm.
A rebound in rainfall is again forecast for Wednesday on the Caribbean slope and dispersed during the afternoon period in the Pacific regions.
Warning: Special attention in the Caribbean and Northern Zone due to the high flow in streams and rivers due to the rains of the last few hours, in addition to saturated soils in mountainous parts such as Route 32. On the other hand, because rains are estimated near the Limón International Airport from today until this Wednesday, there is a high probability of flooding for said sector.
Due to the above, the IMN recommends:
• Caution about overflowing streams and small rivers in places prone to this type of flooding.
• Prevention against electrical storms and seeking shelter in a safe place in case strong gusts of wind occur or are perceived near storm clouds, due to the possible fall of tree branches, power lines, among others.
• Stay informed through social networks, Twitter: @IMNCR, Facebook: National Meteorological Institute CR and the WEB Page: www.imn.ac.cr
Next report: Today Tuesday at 9 p.m.
