Down in the lowlands, Sunday morning was mostly clear skies and thin sunshine. Up in Da Nang's southern mountains, people spent it watching the slopes behind their kitchens.

Heavy rain hit the upland communes of Tra Giap and Nam Tra My around dawn on October 11. Tra Giap's commune chairman, Phung Van Nam, told Tuoi Tre the downpour started at about 6:15 a.m. and didn't ease until close to noon. He estimated about 200 millimeters fell, enough to turn a narrow river basin into what the paper described as a waterfall of brown water.

What broke

At midday Nam said checks had turned up no significant damage. By late afternoon the picture had changed. Bao Da Nang, the city's official paper, reported landslides on several Tra Giap roads, including the road from the Duoc Lieu area to village 4, the road to village 3 and a district road in village 2.

Three households took the hit directly. Two in village 3 had soil slide down onto kitchens and a concrete path. In village 2, an estimated 15 to 20 cubic meters of earth pushed into one home and cracked a wall. Officials helped that family move somewhere safer. Water also topped a low-water crossing in village 2, and the commune's military command strung warning ropes and put up signs to keep people from wading across.

Next door in Nam Tra My, a slide of trees, soil and rock blocked nearly the whole width of the concrete road linking National Route 40B to the Tu Hon residential area in Tak To village, according to Bao Da Nang and commune chairman Tran Van Man's account to Tuoi Tre. Authorities told residents not to cross the slide, to use other routes, and to wait for an official all-clear before the road reopens. Crews have been posted at the site.

No deaths or injuries were reported in either commune.

Why it matters past the mountains

These are the communes that joined Da Nang when Quang Nam province merged into the city in 2025, and they're now the city's front line for rainy-season damage. Sunday's rain followed several days of wet weather. The Central Region Hydro-Meteorological Station's 9:35 a.m. bulletin warned of thunderstorms spreading from the southern mountains toward some northern wards, with possible tornadoes, lightning, hail, gusts and bursts of up to 30 millimeters of rain an hour.

Local officials say they will keep inspecting slopes and flood points. Their advice is basic but worth repeating: don't cross a spillway when the water is high and fast, and if a hillside starts to crack or trickle, leave first and ask questions later.
