Insights

  • The dust mass spans about 1,300 kilometers and is travelling at roughly 80 km/h.
  • A subtropical ridge combined with a cut-off low over Algeria has strengthened eastward winds that transported the dust to the archipelago.
  • AEMET has issued yellow alerts for suspended dust across all Canary Islands until about 20:00 on Wednesday.
  • Calima reduces visibility, soils surfaces and worsens air quality, so children, older people and those with respiratory conditions should avoid prolonged outdoor exposure.
  • Forecasts and satellite data show the plume will weaken and be pushed southwest by trade winds, clearing skies by early Thursday.
