Residents have been urged to exercise caution during heavy rainfall and avoid walking or driving through flooded roads, rivers, bridges and other waterways.
Motorists are advised to reduce speed, maintain a safe following distance and use headlights when visibility deteriorates due to rain.
People are also cautioned against seeking shelter under trees or standing near isolated tall structures during thunderstorms because of the risk of lightning strikes.
Residents living on or below steep slopes, unstable hillsides and areas prone to landslides have been advised to remain alert for warning signs, including cracks in the ground, leaning trees, unusual ground movement and sudden changes in water flow.
Farmers in areas expected to receive rainfall are encouraged to take advantage of improved soil moisture to support agricultural activities while observing appropriate water and soil conservation practices.
Residents are urged to remain vigilant throughout the forecast period and follow official weather updates and safety advisories as conditions evolve.
