Weather Warning
Locally heavy rains this afternoon and early evening
November 29, 2024
10:10 a.m.
Diagnosis: High humidity is present in southern Central America and the presence of factors typical of the change of season (trade winds in the north of the country and the Convergence Zone in the south of the region) translates into precipitation and instability near the coasts of both sides of the country. During the morning there have been scattered showers and downpours towards the North Caribbean, the Osa Peninsula and the Central Pacific coasts, with accumulations in the last 6 hours of 10 - 20 mm with maximums of 35 mm (Puerto Jiménez), in addition to variable rains in the mountains and parts of the North Zone, with accumulations between 5 - 30 mm.
Forecast: The incursion of cloudiness from the Caribbean Sea towards the national territory will prevail, especially in the North Caribbean, the North Zone and the Central Valley. In addition, the proximity of the Convergence Zone will favor rains in sectors of the South Pacific and in low areas near the coasts of the South and Central Pacific. In the afternoon, scattered showers and downpours are expected, locally of strong intensity, for the mountains of the North Caribbean, those of the South Pacific (accompanied by thunderstorms) and most sectors of the Northern Zone. Accumulations would be between 20 - 50 mm with punctual maximums between 70 - 90 mm. The Central Valley, Central Pacific and South Caribbean would have these rains, but in a more isolated manner, with accumulations between 15 - 40 mm with maximums of 60 mm. Towards the end of the afternoon and nighttime period, the occurrence of showers with possible storms is probable near the coasts of the Central Pacific, in the center and west of the Nicoya Peninsula. The estimated amounts in a very localized manner would be between 15 - 35 mm with maximums of 60 mm.
⚠ Attention: The gradual influence of Cold Push #3 is projected from this Saturday and into next week, especially on the Caribbean side of our country. The latest analyses show a panorama of significant rains towards sectors of the center and north of these regions and with greater probability from this Sunday to Wednesday of next week. Be aware of the scenario of recurrent rains for this side in the following updates.
Warning: Special attention in mountainous sectors of the Caribbean, Northern Zone and South Pacific because the basins present saturation levels between 85% to 95%. Therefore, they are sectors vulnerable to the occurrence of incidents.
Due to the above, the IMN recommends:
• Caution due to sewer saturation in places prone to this type of flooding.
• Prevention against electrical storms and seek shelter in a safe place in case of occurrence or perception of strong gusts of wind near storm clouds, due to the possible fall of tree branches, power lines, among others. These gusts can reach 80 km/h in some isolated cases.
