12:00 a.m.

Diagnosis: An extensive low-pressure system - which has been followed up in the last 84 hours - continues to be positioned in the Pacific Ocean, 700 km west of the Guanacaste coast; it keeps the Intertropical Convergence Zone in southern Central America very active, causing rainfall of variable intensity throughout the country. In addition, at this time tropical wave # 2 is located in Panama and continues to move towards Costa Rica.

With a break at 11:30 pm, the maximum accumulated figures recorded this day by region are:

 

Región	Rango de acumulados máximos (en milímetros)
Valle Central	20-70 mm
Caribe Norte	20-33 mm
Caribe Sur	5-17 mm
Pacífico sur	15-42 mm
Pacífico Central	20-57 mm
Pacífico Norte	15-83 mm
Zona Norte	17-20 mm (91 mm en el sector Las Delicias)

 

 

Forecast: The low pressure system has a 60% probability of becoming a tropical depression in 2 days, while heading towards Guatemala and southern Mexico. As long as it remains in its current position, it will be disturbing the Intertropical Convergence Zone (ITCZ), which is located on our territory, contributing humidity and instability to our country. The influence of the ITCZ ??is expected throughout the weekend.

In the Pacific regions, there will be rainfall of variable intensity tonight, with the highest intensities in the southern and coastal Nicoya Peninsula, with estimated amounts between 25-40mm and maximums of up to 60mm tonight; in the Central Pacific between 20-40mm in the same period. Meanwhile, in the Central and South Pacific regions the estimated amounts are between 10-30mm in the same period. Precipitations are expected to extend into the early hours of themorning.

For its part, tropical wave # 2 will continue to advance westward and will reach the country during the early hours of Saturday, increasing the possibility of rainfall of variable intensity in the North Caribbean and the North Zone during the morning as it passes. The influence of the tropical wave will continue only on Saturday.
