In northern Peru’s Tumbes region, surging ravines and flooded neighbourhoods have left homes unsafe and routes difficult to use. A new emergency report provides a firmer count of damage—and important limits on what can yet be said about livelihoods.
Floods spread across Peru’s northern border region
Floodwater and runoff from swollen seasonal ravines have disrupted communities across Tumbes, the small Peruvian region bordering Ecuador. A November 5 update from Peru’s national emergency operations centre, COEN-INDECI, traces incidents from November 1 onward: the Zarumilla River overflowed in Aguas Verdes, while multiple ravines were activated in Pampas de Hospital and the Casitas area. These are documented local emergencies rather than evidence that every part of northern Peru experienced the same degree of flooding.
The report names affected districts in all three Tumbes provinces, including Tumbes, Corrales, San Jacinto, La Cruz, Zarumilla and Aguas Verdes, and describes disrupted roads near Casitas and San Juan de la Virgen. Local newspaper El Comercio separately reported flooded streets and market areas in Tumbes city and access problems around Casitas on November 5. Its description of communities cut off by impassable roads is an on-the-ground account, not a substitute for the official damage census.

What the latest official damage count actually says
At 4:45 p.m. on November 5, COEN-INDECI recorded 324 people classified as damnificadas, a more severe displacement or loss category, and another 808 as afectadas, or otherwise affected. The same provisional table recorded two destroyed homes, 109 uninhabitable homes and 292 other affected dwellings. These categories should not be collapsed into a single count of destroyed houses or homeless residents: their meanings and severity differ.
The report also listed 39 affected educational institutions, one affected health facility and two kilometres of local roads affected. The national report explicitly says local damage-and-needs assessments are still underway. A separate education-sector note in the same document mentions 10 affected school premises, illustrating why different administrative counts should not be casually added together. The regional operations centre reported no loss of life or injuries at the time of that update; that statement is time-bound, not a final casualty determination.

A three-day weather warning, not an open-ended forecast
SENAMHI’s meteorological notice 451 covered November 4 to November 6, warning of heavy to extreme rain on the northern coast, thunderstorms and wind gusts. As reported in contemporaneous coverage of the notice, projected coastal daily totals reached up to 55 millimetres on November 4–5, with a lower forecast range of four to 40 millimetres on November 6. Those are forecast amounts, not measured rainfall totals or estimates of the total water that entered homes.
The warning was described as red for the more severe earlier period and orange for November 6. An earlier briefing reported by El Comercio indicated another pulse of rain could affect Tumbes and Piura through November 7, but that outlook is not the same as a verified extension of notice 451. SENAMHI has since issued notice 456, a red-level warning dated November 5 and in force from November 6 to November 8, forecasting rain of strong to extreme intensity on the northern coast, mainly in Tumbes, with totals of around 100 millimetres per day. That confirms the further pulse of rain reported through November 7 and extends it through November 8 at higher forecast totals.

Evacuations, temporary shelter and emergency access
In Aguas Verdes, the local risk-management office reported 45 displaced families staying at a temporary shelter on a sports court in Villa Primavera and 62 more staying with relatives, according to the November 5 INDECI report. The report describes assessments by municipalities, emergency shelter installation, and evacuation assistance involving local authorities and army personnel. These measures show an active response, but they do not establish that every affected household has received assistance.
Defence personnel were documented helping drain rainwater from Tumbes streets and clear roads and channels in Canoas de Punta Sal, while access remained blocked at the La Angostura and Peña Blanca ravines in Pampas de Hospital. The report also notes temporary power disruption affecting customers in Aguas Verdes, Canoas de Punta Sal and Tumbes. Restoring mobility and electricity matters not only for evacuation but for supply deliveries, medical access and residents attempting to return to damaged homes.

The economic and food-supply question remains open
Flooding can interrupt the journey of food from farms and wholesale routes to neighbourhood markets, especially where smaller roads or drainage channels are compromised. El Comercio reported inundation of the main market and central streets in Tumbes city. That establishes a disruption at a commercial location, but it does not quantify lost food stocks, damaged crops, price rises, lost wages or the number of farmers affected.
No verified agricultural-loss table or food-security assessment attributable to the November 5 COEN-INDECI update was identified in the sources used for this article. It would therefore be misleading to attach a hectare figure, harvest loss percentage or monetary estimate to this event. The defensible conclusion is narrower: housing, transport and local commerce face documented interruptions, while the agricultural and livelihood cost remains unquantified and requires sector-specific follow-up.

What the next assessment needs to establish
Peru’s November 5 emergency report notes that Tumbes had been placed under a state of emergency by Supreme Decree 149-2026-PCM, effective November 4 through January 2, 2027, because of imminent danger linked to intense rainfall associated with El Niño conditions. An emergency declaration supplies a legal framework for response; it is not a forecast that equally intense rain will last for the entire period. The immediate operational test is whether local damage assessments can be completed and roads, homes, schools and services progressively restored.
For residents, the central uncertainty is not simply how many millimetres might fall next. It is whether homes marked uninhabitable can be repaired, which communities remain isolated, whether temporary shelters are adequate, and what verified evidence emerges about livelihoods and crops. Subsequent INDECI situation updates are needed before these provisional figures can be revised; the post-November 6 weather outlook has already been updated by SENAMHI notice 456, which forecasts around 100 millimetres of rain per day on the northern coast through November 8.
