Sluice gates opened as heavy rains spark flood alerts countrywide

Widespread heavy rainfall has prompted authorities to open sluice gates at multiple reservoirs and issue a series of flood warnings across several districts, disrupting transport and placing thousands on alert.

In Moneragala, two spill gates of the Weheragala reservoir were opened by one foot and four more by six inches after water levels rose sharply, Assistant Director of the District Disaster Management Centre (DMC) Ravindra Kumara said. The Menik Ganga has now reached spill level, prompting warnings to pilgrims heading to Kataragama and Sella Kataragama to avoid entering the river.

Traffic along the Wellawaya–Wewelakandura road was also hampered after the Alikota Ara reservoir reached capacity and its spill gates were opened, submerging parts of the route. Officials said water levels in the area rose rapidly due to persistent downpours.

Meanwhile, the Department of Irrigation cautioned of potential flooding within the next 48 hours in low-lying areas of the Mahaweli River Basin. Heavy rainfall in upstream catchments has put several Divisional Secretariat divisions — including Kinniya, Muttur, Kantale, Seruvila, Welikanda, Medirigiriya, Lankapura, Thamankaduwa and Dimbulagala — at heightened risk.

Sections of the Batticaloa–Polonnaruwa road, especially near Gallella, and access routes to the Somawathiya Raja Maha Vihara may become inundated. Devotees have been advised to postpone visits until conditions improve. Residents close to the Mahaweli River have been urged to remain on high alert.

In a separate advisory, a red flood warning was issued for downstream areas of the Gal Oya following intense rainfall that pushed the Senanayake Samudraya in Inginiyagala to full capacity. Authorities warn that opening the spill gates could trigger major flooding downstream, affecting communities in Damana, Ampara, Eragama, Addalaichenai, Sammanthurai, Nintavur, Karaitivu, Sainthamaruthu, Kalmunai and Navithanveli, as well as low-lying zones near the South Eastern University in Oluvil.

Disaster Management authorities have called for immediate preparedness and urged the public, particularly motorists and residents in vulnerable areas, to take precautionary measures as adverse weather conditions persist.

Nasa spacecraft weighing 1,300lb due to re-enter Earth’s atmosphere

A Van Allen Probe spacecraft weighing more than 1,300lb (600kg) is expected to re-enter Earth’s atmosphere almost 14 years after its launch, Nasa says.

The spacecraft is projected to re-enter around 19:45 EDT (23:45 GMT) on Tuesday the US Space Force predicted, according to Nasa, though there is a 24-hour margin of “uncertainty” in the timing.

The Van Allen Probe A, which launched in 2012, is expected mostly to burn up as it travels through the atmosphere, though some components may survive.

The space agency said there is a one in 4,200 chance of being harmed by a piece of the probe, which it characterised as “low” risk.

The spacecraft and its twin, Van Allen Probe B, were on a mission to gather unprecedented data on Earth’s two permanent radiation belts.

It was not immediately clear where in Earth’s atmosphere the satellite is projected to re-enter. The BBC has contacted Nasa for further detail.

Nasa and the US Space Force have said they will monitor the re-entry and update any predictions.

The mission, which was originally designed to last two years, went on for almost seven. It ended after the spacecrafts ran out of fuel and were no longer able to orient themselves toward the Sun.

The probes flew through rings of charged particles trapped by Earth’s magnetic field from 2012 to 2019, in order to study how particles were gained and lost, per Nasa.

Those rings, called the Van Allen belts, shield Earth from cosmic radiation, solar storms and streaming solar wind, which are harmful to humans and can damage technology.

The mission made significant discoveries, including the first data that show the existence of a transient third radiation belt, which can form during times of intense solar activity, Nasa said.

Van Allen Probe B is not expected to re-enter the Earth’s atmosphere before 2030.

Prime Minister Dr. Harini Amarasuriya visited the International Rice Research Institute (IRRI) headquarters in Los Baños, Laguna, Philippines, on 11 March 2026, and held bilateral discussions with Yvonne Pinto, Director General of IRRI, focusing on strengthening cooperation in the field of rice research and sustainable agricultural development.

During the meeting, discussions centered on rice cultivation in Sri Lanka, including the key challenges faced by Sri Lankan paddy farmers. The Prime Minister highlighted issues affecting the sector such as productivity constraints, climate-related impacts, and the need to support farmers through improved agricultural practices and technological innovations.

Both sides also discussed the importance of introducing modern techniques and research-driven approaches to rice cultivation in order to enhance productivity and ensure long-term food security. In this regard, IRRI shared insights on ongoing global research initiatives aimed at improving rice varieties, strengthening climate resilience, and promoting sustainable farming practices.

The discussion further focused on the potential for expanded collaboration between Sri Lanka and IRRI, particularly in areas such as research partnerships, knowledge sharing, and capacity building for Sri Lankan agricultural institutions and farmers. The Prime Minister emphasized Sri Lanka’s interest in strengthening cooperation with IRRI to support the development of the country’s rice sector and to improve the livelihoods of paddy farmers.

The visit reaffirmed the importance of science-based agricultural innovation and international collaboration in addressing food security challenges and enhancing sustainable rice production in Sri Lanka.
