PETALING JAYA: Several areas in Sabah and Sarawak have been placed under a Level 1 heatwave alert, according to the latest monitoring update by the Malaysian Meteorological Department (MetMalaysia).
As of 6am on Thursday (Aug 13), Kudat and Telupid in Sabah, alongside Marudi, Sri Aman and Lubok Antu in Sarawak, were marked yellow on MetMalaysia's monitoring map.
A Level 1 warning is triggered when daily maximum temperatures range between 35°C and 37°C for at least three consecutive days.
No areas in Peninsular Malaysia were under a heatwave alert, with the entire region categorized in blue, indicating daily maximum temperatures remained below 35°C.
Level 2, or Heatwave, is declared when daily maximum temperatures range between 37°C and 40°C for at least three consecutive days.
Level 3, or Extreme Heatwave, applies when daily maximum temperatures exceed 40°C for at least three consecutive days.
The latest alert areas were concentrated in northern Sabah and interior parts of Sarawak, while the rest of both states remained below the warning threshold.
MetMalaysia notes that heatwave classifications are determined by sustained maximum temperatures over consecutive days rather than single-day readings.
