Weather Warning (Update)
Variable precipitations this thuesday in the country
May 10, 2024
6:00 p.m.
Diagnosis: Unstable atmospheric conditions remain south of Central America due to the activity of the Intertropical Convergence Zone. During this afternoon there have been mostly cloudy skies with showers and a thunderstorm in the Central and South Pacific, as well as the Central Valley. Maximum localized amounts of: 50 mm are recorded in Ciudad Colón in the Canton of Mora-San José, 65 mm in La Ceiba-Nicoya, possible higher amounts in the mountains of the southeast of the General Valley and between 25 - 45 mm in the mountains of the South Pacific.
Forecast: For the late afternoon and early evening, localized downpours with storms are expected, these in low parts and near the coasts of the Central Pacific, around the Golfo Dulce, Gulf of Nicoya and near both peninsulas. The estimated amounts will be between 15 - 40 mm with specific maximums between 50 - 70 mm. For the night period, a reactivation of precipitation is expected in the coastal areas of the Southern Caribbean and the center of the Northern Caribbean. Warning: Attention in sectors of the Central Pacific and South Pacific due to humid soils both in low areas and especially in mountainous areas. Be attentive to the development of storm clouds which present their own and significant characteristics such as descending gusts, high precipitation intensity in short periods of time and electrical discharges.
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 80 km/h in some isolated cases.
