Tehran Meteorological Office Forecasts New Precipitation System and Air Quality Fluctuations

TEHRAN, Oct 14 (OPA) — The Tehran Meteorological Department has announced the arrival of a new precipitation system expected to impact the province starting Saturday night. Hamidreza Khorshidi, the Director-General of the provincial meteorological office, confirmed that while the capital will experience mostly cloudy to partly cloudy skies over the next five days, scattered showers are anticipated, particularly in the northern and higher-altitude regions of the province.

Regarding air quality, Khorshidi noted that a yellow-level pollution warning issued on October 12 remains in effect. Due to a lack of significant wind, central and southern districts of Tehran are experiencing a decline in air quality, a condition expected to persist through Friday afternoon. Khorshidi stated, "Due to the absence of significant wind, a relative decrease in air quality is predicted in high-traffic urban areas, especially in the central and southern parts of Tehran."

Meteorological models indicate that atmospheric stability will be interrupted by moderate to relatively strong winds on Wednesday and Friday afternoons, particularly in the southern and western regions. These winds, while potentially causing temporary dust in border areas, are expected to assist in dispersing pollutants. Furthermore, the forecast suggests that stronger winds in the mountainous regions will contribute to a gradual improvement in overall air quality for the capital.

Looking ahead, the meteorological office predicts a relative increase in temperatures by Friday, specifically affecting the southern and central parts of the province. Residents are advised to monitor official updates as the weather transitions from the current period of atmospheric stagnation to the incoming precipitation system. The combination of shifting wind patterns and temperature fluctuations marks a period of dynamic weather for the Tehran metropolitan area as it moves into the weekend.
