Sri Lanka issues Red Alert as flood threat grows, death toll rises to two
COLOMBO – Sri Lanka’s Department of Meteorology on Friday (15) issued a red alert for heavy rainfall across several parts of the island as intense showers, rising river levels and flooding threats continued to disrupt normal life, leaving two people dead and thousands affected.
The Meteorology Department said a low-pressure system located northeast of Sri Lanka continued to influence weather conditions across the country, although the system is expected to gradually move away within the next 36 hours.
Authorities warned that very heavy rainfall of around 150 millimetres could occur in parts of the Western, Sabaragamuwa and North-Western Provinces, while rainfall exceeding 100 millimetres was also forecast for areas in the Southern Province, particularly the Galle and Matara districts.
The public has been advised to take precautions against possible damage caused by heavy rain, strong winds and lightning associated with thundershowers.
The highest rainfall recorded during the 24-hour period ending at 9.30 a.m. on Friday was from Penrith Estate in Avissawella, which received 175 millimetres of rain. Other areas recording significant rainfall included Veyangoda and Maliboda in the Gampaha District with 162 millimetres and 125.5 millimetres respectively, and Kirindiwela, Pambegama Estate and Talduwa in the Kegalle District with 157 millimetres, 135 millimetres, 131 millimetres respectively,
The adverse weather has already caused widespread disruption across the island.
According to the Disaster Management Centre (DMC), the death toll from the inclement weather rose to two after a second fatality was reported from the Chankanai area in Jaffna. The first death had earlier been reported from Koralepatthu South in Batticaloa District.
The DMC said 3,475 people from 1,113 families across eight districts had been severely affected by the prevailing weather conditions.
A total of 104 people from 29 families have been relocated to two temporary safety shelters, while 88 houses across seven districts have sustained partial damage.
Kalutara District recorded the highest number of damaged houses with 40 affected homes, followed by Batticaloa with 25 houses, Ratnapura with nine, Galle and Colombo with five each, and Monaragala with four.
Meanwhile, the Department of Irrigation issued a minor flood warning for the Kuda Ganga sub-basin of the Kalu River for the next 48 hours following heavy rainfall in upstream catchment areas.
The department warned that low-lying areas along the Kuda Ganga and Maguru Ganga valleys in the Bulathsinhala, Madurawala and Palinda Nuwara Divisional Secretariat Divisions could experience minor flooding.
Residents living in flood-prone areas and motorists travelling through inundation-prone roads have been urged to exercise caution.
Director of Irrigation (Hydrology and Disaster Management) Engineer L. S. Sooriyabandara that although water levels in the Kelani River have been rising steadily since Wednesday (13) night, they had not yet reached official warning levels.
He also noted that the Dunamale gauging station along the Attanagalu Oya had recorded 176 millimetres of rainfall, while Giriulla received 172 millimetres, causing a rise in water levels in the Maha Oya basin.
Heavy rainfall between 50 and 100 millimetres was also recorded in the Gin, Nilwala and Kalu river basins, contributing to rising water levels in several waterways across the island.
Authorities warned that heavy rains are likely to continue throughout the day, especially in the wet zone, and urged residents in low-lying and riverine areas to remain vigilant and closely follow official warnings.
The Irrigation Department also said 21 major reservoirs and more than 19 medium-scale reservoirs across the country were currently spilling due to rising water levels.
Among the major reservoirs releasing water are Rajanganaya, Nachchaduwa and Yan Oya in Anuradhapura District; Lunugamvehera, Tissa Wewa and Weheragala in Hambantota District; Deduru Oya in Kurunegala District; Nalanda and Wemedilla in Kandy District; and Inginimitiya and Thabbowa in Puttalam District.
Large volumes of water are being discharged downstream after sluice gates were opened at several reservoirs. Rajanganaya reservoir alone was releasing more than 1,600 cubic feet of water per second into the Kala Oya, while Lunugamvehera was releasing over 1,740 cubic feet per second into the Kirindi Oya.
Authorities cautioned communities living downstream of reservoirs and near rivers to remain alert as rising water levels could pose flood risks.
Meanwhile, the heavy rainfall also disrupted educational activities in parts of the hill country.
A special holiday was declared on Friday for all schools within the Hatton Education Zone following instructions issued by the Central Province Education authorities.
School principals in the Nuwara Eliya Education Zone were also granted discretion to take necessary action depending on local weather conditions.
