The Southern Regional Hydro-Meteorological Centre forecast scattered showers and thunderstorms across HCM City and southern provinces on November 2, particularly in the afternoon and evening.
Temperatures are expected to range from 23-26 degrees Celsius overnight to 31-34 degrees during the day. Residents have been warned of thunderstorms accompanied by whirlwinds, lightning and strong wind gusts.
According to the weather agency, a very strong El Nino is expected to persist throughout November, while successive cold air outbreaks from mainland China will have only a limited impact on southern Vietnam.
During the first 10 days of November, an equatorial trough combined with upper-level wind convergence could bring rain to the region.
From mid-November, however, a southward shift in the subtropical high-pressure system is expected to reduce rainfall, bringing the rainy season to an end during the first half of the month.
Average temperatures in southern Vietnam are forecast to be 0.3-1 degree Celsius above the long-term average.
Daytime highs will generally range from 30-33 degrees Celsius, occasionally reaching 34-36 degrees, while overnight lows will mostly be 24-27 degrees, falling below 24 degrees in some northern parts of the region.
November rainfall is expected to be near or below the long-term average, with central HCM City potentially receiving 10-30 per cent less rain than usual.
Most rainfall is forecast during the first 10 days of the month, with around eight to 13 rainy days expected overall.
Over southern coastal waters, the northeast monsoon is forecast to be moderate to strong. The weather agency also considers tropical cyclone activity in the East Sea unlikely during November.
Residents have been advised to remain alert to thunderstorms, whirlwinds, lightning and strong gusts, while vessels could face hazardous conditions during periods of strong northeast monsoon winds.
