Heavy showers are likely over the next 24 hours, particularly in the southwestern parts of the island, the Department of Meteorology said.
Heavy falls of about 100 to 150mm are expected in the Western, Sabaragamuwa and Central provinces as well as in the Galle district, while fairly heavy falls between 75 to 100mm are likely in the Eastern, Uva and Northern- Western provinces and in the Matara district.
In a notice issued to the public today, the Met Department warned that heavy rains may trigger landslides in hilly areas and water inundation is expected in low-lying parts of the country. Large avenue trees may also be uprooted.
The Met Department recommends that people living and driving in hilly areas, particularly landslide-prone areas, be vigilant. It also asks that people take adequate precautions to minimise damages caused by lightning activity.
“Beware of fallen trees and power lines; be alert on Met Dept advisories; and contact the local disaster management authorities for emergencies,” the statement said.
Meanwhile, the Disaster Management Centre (DMC) has issued a red alert to people residing near Kumbukkan Oya, Hoda Oya and Mahaweli Ganga due to increased water levels.
The DMC also issued a landslide red alert to all the residents living in areas such as Matale (Laggala–Pallegama), Kandy (Ududumbara) and in Nuwara Eliya (Walapne) districts.
“The general public is kindly requested to take adequate precautions to minimise damages caused by temporary localised strong winds and lightning during thundershowers”, warned the Met Department.
