Saharan Dust Brings Dry Conditions and Heat Wave to Central American Peninsula

A large Saharan dust plume is expected to arrive this weekend, bringing drier air into the mid‑troposphere over the Central American peninsula. Meteorologists forecast that precipitation will become lighter and more isolated, with total rainfall remaining unchanged but spread over a longer period. The dust will suppress storm development, leading to clear skies with occasional orange‑yellow sunrise and sunset hues.

Temperatures are projected to rise to 40 °C or higher in some areas, while high humidity will push the perceived heat index to between 45 °C and 50 °C, raising the risk of heat‑related illnesses. Authorities advise precautions against heatstroke. The dust layer, situated above 2 km, poses no direct health threat. It is expected to thin out gradually from early next week, easing the dry spell.

The event also marks the onset of a mild Canícula period, which will further limit rain intensity despite occasional isolated showers.
