The Central Meteorological Observatory has issued a forecast indicating that southern Tibet will experience intense rain and snow from October 30 to October 31, with local areas potentially facing extra-large blizzards. 1 This severe weather pattern is driven by the interaction of a cyclonic residual vortex and an upper-level trough. 1 Simultaneously, northern regions including Northeast China, northern North China, and parts of Inner Mongolia are expected to undergo strong winds and significant cooling. 1
In southern Tibet, valley lowlands are predicted to see heavy to torrential rain, while higher altitudes will face blizzard to heavy blizzard conditions, with some locations possibly experiencing extra-large blizzards. 1 Cumulative precipitation in these areas is estimated at 20 to 40 millimeters, with localized amounts reaching 50 to 80 millimeters, and maximum cumulative snowfall projected between 20 and 40 millimeters. 1 Meanwhile, cold air activity will persist through November 2. 1 In affected northern zones, temperatures are expected to drop by 4 to 8 degrees Celsius, with decreases exceeding 10 degrees Celsius in some parts. 1 These regions will also endure northerly winds of force 4 to 6, with gusts reaching force 7 to 9. 1
At 06:00 on October 30, the Central Meteorological Observatory continued its blue alert for strong winds. 1 The warning extends to maritime areas, where the Bohai Sea, the Bohai Strait, and the northern Yellow Sea are expected to experience winds of force 7 to 8, with gusts up to force 9. 1
