Wednesday was a typical rainy season day with 120 homes flooded, trees falling and four roadways and two bridges out of service.
The Instituto Meteorológico Nacional said that the low pressure system that caused all this has moved into Nicaragua and weakened, but forecasters expect the system to strengthen again once it starts to pass over the Pacific Ocean.
There was much more rain through 7 a.m. Wednesday than afterwards, although there were showers in places most of the day in the Central Valley. Escazú got 77 millimeters between 7 a.m. Tuesday and 7 a.m. Wednesday. That’s a bit more
than three inches. But the rainfall was just 10 millimeters since 7 a.m. Wednesday.
The bulk of the flooding was in the usual spots with Puntarenas Centro leading the way. The national emergency commission said that 19 cantons had places where there were problems. These may have been nothing more than storm sewers backing up and low spot in the highway filled with water.
The problems were not unexpected because the low pressure system was over the Caribbean and moving east Sunday.
The weather institute said that forecasters expected the low pressure system to move into the Pacific and relax its grip on Costa Rica by early Friday.
