Castilla y León Issues Alert for Saharan Dust Episode From Tuesday

Officials warn air quality may become very unfavorable as PM10 24‑hour averages could exceed 50 µg/m³, prompting targeted health guidance.

Overview

  • The regional advisory says dust from northern Africa will affect the entire community from February 24 for at least three days.
  • Authorities describe the intrusion as a natural phenomenon not subject to direct control, focusing the response on reducing exposure.
  • People in risk groups are urged to limit strenuous outdoor activity, follow prescribed treatment plans, and watch for cough, throat irritation, shortness of breath, fatigue, or palpitations.
  • Because concentrations will vary by hour and location, residents are advised to check local air‑quality information before outdoor plans.
  • To minimize added particles, officials recommend avoiding outdoor burning of plant waste and other activities that generate emissions, noting Spain and EU rules set no specific public‑information threshold for this pollutant.
