With weak cold air arriving in the city, showers or thunderstorms will be experienced in some areas from Friday afternoon. Short bursts of rain could reach 30 millimeters per hour, and a maximum wind force of 102 kilometers per hour will be strong enough to damage buildings.

The weather over the five-day Labor Day holiday from Saturday will be warm and the air quality good.
