In the next 24-48 hours, the continental high pressure will continue to weaken. A low pressure trough connecting to the hot low pressure area in the West will be re-established, crossing the North and tending to gradually become stronger.
Above, the subtropical high pressure lowers its axis to the South, crossing the Central, South Central and Southern regions, while high-altitude disturbances weaken.
From now until about 10 days, the low pressure trough connecting to the hot low pressure in the West will be more active and gradually compressed to the South. Above, the subtropical high pressure has its axis passing through the South Central and Southern regions, then gradually rising to the North.
From around May 16, this system weakened, withdrew and lowered its axis to the South; around May 20-21, it tended to encroach westward, raising its axis back through the South Central Coast and the South. High-altitude turbulence became stronger, then weakened from around May 20.
Due to the influence of the above weather patterns, the Southern region continues to experience widespread hot weather in the next 24-48 hours. The highest temperature is commonly from 35-37 degrees C, the lowest humidity is about 40-50%. The hot weather lasts from about 11-16 am daily and is likely to last until the end of May 15.
The meteorological agency warns that hot weather combined with low air humidity increases the risk of fires and explosions in residential areas and forest fires. Prolonged hot weather can also cause dehydration, exhaustion, and heat stroke if exposed to the outdoors for a long time at high temperatures.
