General Review

The passage of the cold surge #11 through the north of the Caribbean Sea basin will be increasing the probability of rain in sectors of the Caribbean and parts of the Northern Zone between Thursday and Friday. Additionally, it will present an increase in the trade winds, with occasionally strong gusts, starting this Thursday in the north of the country, and over the Central Valley, low parts of Guanacaste, and central mountainous sectors from this Friday into the weekend. From Saturday onwards, the arrival of a dry air mass and the presence of high-pressure systems over our region would be establishing stable conditions, with less cloud cover and maintaining warm temperatures towards the Pacific slope.

Forecast

• Mornings: For the first two days of the forecast, the cloudiness ranges from little to partly cloudy over the Central Pacific and South Pacific regions, while in the Caribbean regions, the cloudiness would be variable with a probability of occasional rain-showers. From Saturday onwards, there would be partial to little clouds in the Caribbean and sunny conditions for the Pacific.

• Afternoons: Very localized showers and downpours in the Central Pacific, mountainous South Pacific, and surroundings of the Golfo Dulce, being more evident at the beginning of the considered period. Partial to mostly cloudy in the Caribbean regions and the Northern Zone, with possible occasional rain-showers near and over the mountains on Thursday and Friday, then presenting few and partial clouds over the mountains from Saturday onwards.

• Nights: Cloudy to partly cloudy from Thursday to Saturday for the Caribbean. Between cloudy to partly cloudy in the Central Pacific, South Pacific. Clear from Sunday onwards.
