In the context of climatic phenomena such as the El Niño-Southern Oscillation (ENSO), which has triggered floods in the basins of northern coastal Peru, resulting in building destruction, thousands of affected individuals, and infrastructure damage, the National Meteorology and Hydrology Service of Peru (SENAMHI) produces the “hydrological advisory.“ This product provides information on the exceeding of three danger level thresholds: yellow, orange, and red, in the face of potential river overflows or fluvial erosion. It plays a crucial role within the National System for Disaster Risk Management (SINAGERD) for decision-making in response to the danger of hydrological floods. During my tenure at the National Emergency Operations Center (COEN), the validation of this product was conducted by comparing the issuance periods of these advisories with events in the Tumbes River basin. Events of extreme hydrological nature recorded by official institutions such as the National Water Authority and INDECI were compiled. Additionally, freely accessible satellite images from Sentinel 2 and LandSat 7 and video material from various national and local media outlets were used. With all this collected information, the validation of hydrological advisories issued from March 7 to May 1, 2023, in the Tumbes basin was carried out. The results indicated that the red danger threshold was not appropriate, leading to its adjustment from 1000 to 900 m³/s. The validation showed a satisfactory hit rate of 0.95 and a miss rate of 0.07, resulting in an overall improvement in the effectiveness of the advisory and subsequent recommendations based on the experience gained at COEN.
