There may be one more day without major thunderstorms

The country has experienced three days of mostly sunny skies with only a small amount of rain.

But the Instituto Meteorológico Nacional said Sunday that the weather soon will turn to the usual for the rainy season: Hot and sticky mornings giving way to thundershowers in the afternoon.

There still is a pretty good chance that Monday will be the fourth day in a row of just isolated showers. The weather institute said that winds from the east generally inhibit rain in the Central Valley and the Pacific. But there is a good chance of some rain in the Caribbean and northern zone.

There were only a few millimeters of rain in the country
Sunday. Some places got no rain. Turrialba with 6.5 millimeters appeared to be the wettest, based on the institute’s automatic weather stations. That is about a quarter inch.

Isolated rains Sunday morning were caused by the passage of a tropical wave over the national territory, said the weather institute. This was tropical wave No. 6 for the season. These are low pressure troughs that form west of the Atlas Mountains in Africa and sweep across the tropical latitudes.

The tropical waves can bring heavy rains, but not this one.

There was some rain in Limón but nowhere near the heavy downpours the weather service warned about in a morning bulletin.
