5:15 p.m.

Diagnosis: A wide region of instability over all of Central America, due to large-scale forcing along the Intertropical Convergence Zone and the passage of tropical waves, has caused heavy downpours to occur this Saturday in our country in coastal areas of the South Pacific and North Pacific, in addition to cloudy conditions with variable rainfall in the Central Valley, Central Pacific and downpours with storms in the Northern Zone and mountainous parts of the Caribbean.

In the last 12 hours the accumulated rainfall recorded by region is: for the North Pacific between 30 – 50 mm with maximums of 90 mm (Tamarindo), for the South Pacific between 10 – 40 mm with a maximum of 118 mm (Osa), in the Central Valley and Central Pacific between 10 – 50 mm, while the regions of the western Caribbean along with low parts of the Northern Zone, record accumulated rainfall between 5 – 40 mm.

Forecast: Localized showers are expected to continue in the late afternoon in low areas and near the Caribbean coasts. Accumulated amounts will be between 10 - 40 mm with maximums of up to 65 mm. In the case of the Pacific side, there will be occasional cloud cover and the possibility of moderate rain during the late afternoon and evening hours. Accumulated amounts will be between 10 - 40 mm.

For the early morning period, scattered showers are expected to occur again on the coasts of the Central Pacific, the North Pacific and around the Golfo Dulce. Accumulated amounts will be between 30 - 50 mm with maximums of 70 mm.

For the Central Valley, the probability of moderate to light rain will continue until Sunday, with scattered fog today, along with fog banks during the early morning and Sunday morning.

Warning: The rains forecast for the Pacific coastal sector and low-lying areas could cause flooding due to overflowing rivers and ravines (peninsular areas). Possibility of landslides on saturated soils in the mountains of the South Pacific, Central Pacific and western Caribbean.

Due to the above, the IMN recommends:

• Caution due to sewer saturation in places prone to this type of flooding.

• Prevention in the event of an electrical storm and seeking shelter in a safe place in the event of strong gusts of wind occurring or perceived near storm clouds, due to the possible fall of tree branches, power lines, among others. These gusts can reach 80 km/h in some isolated cases.
