The provinces of Gilan, Mazandaran, and Golestan will also experience showers and occasional thunderstorms due to the continued humidity from the Caspian Sea. In these areas, the intensity of the rains may reach a level that causes flooding of pathways and an increase in runoff.
Areas Prone to Rain in North Khorasan and Razavi Khorasan
In North Khorasan and the northern half of Razavi Khorasan, conditions are also favorable for rainfall, showers, and thunderstorms. In the northeastern heights of the country, due to upward air movement and the influx of moisture, there is a possibility of forming rain cells. These phenomena can have significant impacts on the daily lives of people in these areas.
In Tehran province, widespread rainfall is not expected throughout the province, but the heights and northern slopes, especially along the central Alborz, may witness increased cloudiness, showers, and thunderstorms. Additionally, the provinces of Alborz and Qazvin will also be affected by atmospheric instability.
Semnan will also experience a likelihood of increased cloudiness and atmospheric instability, especially in the northern regions and heights. In contrast, larger areas of the central and southern parts of the country will generally face more stable weather. However, temporary strong winds, dust storms, and reduced air quality are likely in the northern and southern slopes of Alborz and the northeastern and eastern parts of the country.
In terms of weather mechanisms, the continued humidity from the Caspian Sea alongside upward air movement over the Alborz slopes is considered the main factor enhancing rainfall in the northern country. This weather situation can have various impacts on agriculture and water resources in the northern provinces and requires appropriate attention and planning from the relevant authorities.
