Weather Warning

Rain will extend into the first part of the night

May 09, 2024
05.15 p.m.

Discussion: The Intertropical Convergence Zone is located over the country, which generates a significant contribution of humidity and instability and has caused rainy conditions this afternoon in the Pacific, Central Valley and mountains of the Northern Zone. The highest accumulated so far are: Heredia 57 mm, Fraijanes 41 mm, Santa Cruz 33 mm, Orotina 27 mm, Puerto Jiménez 12 mm, among others.

Forecast: In the remainder of the afternoon and early evening, the presence of isolated showers and electrical storms will continue in the North Pacific, Central Valley and mountainous parts of the Northern Zone, amounts between 25-50 mm with possible higher accumulations of localized manner. For its part, in the Central and South Pacific, rains of variable intensity and scattered electrical storms are estimated, extending in the middle of the night period, accumulated between 45 - 65 mm with specific maximums between 65 - 105 mm.

Warning: Attention in sectors of the North Pacific (around the Gulf of Nicoya and the mountainous southeast), Central Pacific and South Pacific due to humid soils both in low parts 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 thunderstorms.

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.
