The weather in San José this morning, Friday, sucks. The city woke up to grey skies and light rain, in total contrast to blue skies and sunshine.

QRecommendation:

If going out, make sure you have an umbrella. Galoshes  or other weather proof footwear is a good idea also. If driving, ensure your tires have good thread, the windshield wipers are in good condition and work and keep your distance from other vehicles.

A good rule of thumb, don’t drive over that pothole – or step into one, if you are walking in the rain. You never know how deep it really is until …

The Instituto Meteorológico Nacional (IMN)- the national weather service – tells us that that will be norm for the coming days. Rain. More rain. And then some more rain.

In the mornings we can expect light rain. In the afternoons “aguaceros” (downpours) and possibly lighting and thunder.

The areas most affected are the Central Valley, the Caribbean and the Northern Regions (ie. San Carlos, Sarapiquí, etc).

The IMN recommends keeping an eye on the weather and a strict vigilance against possible flash floods from storm sewers, rivers and creeks. The heavy rain also may be the cause of landslides in many areas.

The IMN explains the cause the foul weather is the proximity of the Zona de Convergencia Intertropical (Intertropical Convergence Zone –  ITCZ), the area encircling the earth near the equator where the northeast and southeast trade winds come together.
