Meteorological Warning

Rainy conditions over the South Pacific during the afternoon

September 19, 2023

10:30 a.m.

Diagnosis: A high humidity content and diurnal warming in conjunction with the position of the Intertropical Convergence Zone generates unstable conditions over the country. During the morning, a low cloud environment is observed for the Pacific and Central Valley. For the Northern Caribbean and Northern Zone a partly cloudy sky.

Forecast: For the afternoon and early evening, significant accumulations are forecast for the South Pacific due to downpours and the possibility of a thunderstorm. Estimated amounts between 30-70 mm with possible localized higher amounts.

Isolated showers are expected in the Central Pacific, Nicoya Peninsula and mountainous areas of the North Pacific in the afternoon and early evening. Estimated amounts between 20-50 mm with possible localized higher amounts.

For the Central Valley, isolated showers are expected with the probability of an intense electrical storm to the west and north of the region. Maximum amounts estimated between 10-35 mm with the possibility of localized higher values.

For the Caribbean and Northern Zone, isolated showers are expected during the early afternoon in the border area and mountainous sectors. Estimated amounts between 15-35 mm and possible specific accumulations between 35-45 mm.

Warning: Special attention to the South Pacific, in the Osa Peninsula, the border area with Panama and around the Talamanca mountain range, because these areas have high levels of soil saturation, which increases the risk of incidents.
 

• Due to the above, the IMN recommends:
• Caution due to sewage saturation 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. These gusts can reach between 80 to 100km/h in some isolated cases.
