Remind everyone to arrange travel reasonably
Remember to bring rain gear when you go out
Pay attention to clothing to keep warm
Like sanitation workers, couriers, delivery workers, traffic police, etc
Outdoor staff should pay more attention to windproof and warm when they leave early and return late
The public in coal-fired heating areas needs to pay attention to the safety of heating with fire
Protection against carbon monoxide poisoning
Defensive Guidance
1. The government and relevant departments shall make preparations for cold tide and high winds at sea in accordance with their duties;
2. Do a good job in windproof, anti-low temperature and anti-freeze work;
3. Take active countermeasures for water operations in relevant waters and passing ships to strengthen port facilities and prevent ships from anchoring, stranding and collisions;
4. Strengthen facilities for agriculture, trellises, billboards and other structures, stop outdoor dangerous operations such as open-air activities and high altitudes, and try to turn to sheltered places as much as possible.
Facility agriculture impact assessment and production recommendations
On the 19th, most of the province had good light, which was conducive to the photosynthetic growth of facility vegetables.
On the 20th and 21st, most areas have light rain, there is light snow in the peninsula area, and the relative humidity of the air in the facility is large, it is recommended to ventilate and drain moisture in a timely manner to prevent the occurrence of vegetable diseases in the facility.
Affected by the strong cold air on the 21st, the external ambient temperature is significantly reduced, and the gusts in most areas are larger, it is recommended to strengthen the management of agricultural production, and the facilities are covered with thermal insulation covering materials at night; the shed film pressure line is pressed in advance, and the vent is closed when the wind is strong, so as to prevent the facility shed film from being damaged.
