For the second half of this month, the North Pacific will fully receive the rainfall, which in recent days has also begun to be felt more strongly in Santa Cruz, Nicoya, Liberia, Hojancha and other cantons.

Once the aquifers recover, the rationing that residents of Hatillo, Alajuelita and other sectors have been facing will cease.
The South Pacific was the first region of the country to receive the 2022 rainy season, starting in March. The CNE and IMN confirm that the area is the one with the most saturated soils, which means that very strong downpours are not necessary for the rivers to grow and overflow.
For today, Tuesday, May 3, the IMN forecasts: The atmospheric pattern prevails unstable over the country and its surroundings, a situation caused by the proximity of the Intertropical Convergence Zone, the above, together with the high morning warming, will cause an ideal environment for the occurrence of precipitation. The rains will be present especially during the evening period and part of the night in the Pacific, Central Valley, mountains of the North Zone and the Caribbean.
