The weather forecast for the weekend is wet.
In fact, there is a good bet that most afternoons until late November will have rain.
The Instituto Meteorológico Nacional says that today the typical pattern will prevail. Warm mornings will boost the uptake of moisture that then will fall as thunderstorms in the early afternoon.
The weather service said there was rain Thursday night between Dominical and Uvita. Caution was urged.
The weather service in San José also warns of stiff winds created by the thunderstorms.
For expats, the major concern should be protection of computers and electronic gear. There is no system that can protect from a direct lighting strike, so the best bet is to unplug devices when thunder is near.
Golfers have their own worries, which is why the 19th hole was created.
