Under the continuous influence of cold air, all districts fell below 0 degrees in the morning! The minimum temperature at Xujiahui Station in the urban area fell to minus 2.3 degrees (falling below freezing for the first time in the second half of this year), and the lowest temperature in Chongming was only minus 4.4 degrees, the lowest in the city.
The temperature rises slightly, but the rain and snow return
Today's temperature has risen slightly, with a minimum of 1 degree Celsius and a maximum of 6 degrees, but it will also be followed by rain and snow! Affected by the low-level shear line, there will be a short period of light sleet in the western and southern suburbs around the morning, and it will be cloudy with light rain in the morning.
Overall, although there is a slight increase in temperature today, it may feel colder in the body, and it is a "magic attack" that freezes to the bone marrow. Everyone must dress warmly when going out, and pay attention to road traffic safety.
The cold sensation continued into Tuesday. From Wednesday, a new round of cooling has begun, although the dry cold air has driven away the rain, but the cooling is inevitable, and the minimum temperature on Thursday and Friday will fall to minus 3 degrees to minus 2 degrees.
The cold wave hit, and the number of frostbite patients in many places has increased in the past few days. Frostbite is an injury caused by cold temperatures, and the lower the temperature, the wetter the locality, and the stronger the wind, the more severe the damage.
In cold weather, pay attention to protect the ears, nose, hands, feet and other peripheral parts, and avoid prolonged exposure in cold environments. Humid conditions are more likely to cause frostbite on tissues, so it is necessary to change clothes in time after exercising and sweating.
Doctors pointed out that the "dirt method" of scrubbing frostbite with snow water is unscientific, which can aggravate tissue damage. If you notice frostbite, get out of the cold as soon as possible. The most urgent treatment in the early stage is to quickly rewarm with warm water at 40°C~42°C. For example, if your hands are frostbitten, soak your hands in warm water for about half an hour, and soak them until your hands become red and soft.
If the limb is frostbitten, avoid pressure and elevate to reduce edema. If you experience symptoms such as redness, swelling, increased pain, or bluish skin color, you should seek medical attention promptly.
