Informative Weather Advisory

Saharan Dust and Strong Wind Gusts Affecting Several Regions

July 15, 2025
9:00 am

 

A dry air mass accompanied by Saharan dust is positioned over the Caribbean Sea and Central America. Additionally, a marked atmospheric pressure gradient is accelerating the trade winds in the region. These factors are promoting windy and mostly stable conditions across the country, as well as the presence of haze in central and northern regions of the national territory.


Throughout Tuesday, moderate to strong wind gusts are expected in the central and northern parts of the country, as well as in the mountain ranges, with speeds ranging from 35 to 60 km/h and from 60 to 85 km/h, respectively. This windy pattern is expected to persist for most of the week.

Regarding the Saharan dust, its presence is projected to be more concentrated between Tuesday and Wednesday, with a significant decrease starting Thursday. This will allow for increased humidity and a higher likelihood of rainfall heading into the weekend.

 

Given the above, the IMN recommends:
