Context & Explainers
Carbon monoxide (monóxido de carbono) is a colorless, odorless gas produced when fuels burn incompletely (gas, wood, petrol, diesel, generators). It binds to blood and reduces oxygen delivery, causing headache, dizziness, nausea and can be fatal; if you suspect exposure, get fresh air immediately, call emergency services (112) and seek medical attention. For home safety, install battery-backed CO detectors and have heating appliances and chimneys inspected annually.
A yellow warning is the lowest alert level in IPMA's four-tier color-coded weather warning system (green → yellow → orange → red). It signals weather conditions that are potentially dangerous but not unusual for the region and season.
Yellow warnings are issued for moderate rainfall, gusty winds (typically 60–90 km/h), moderate heat, or waves above 4 meters. They are district-specific and time-limited. While they do not typically require emergency measures, they indicate conditions that could cause localized disruption — slower traffic, minor flooding in low-lying areas, or isolated power outages.
When a yellow warning is active, residents should take common-sense precautions: secure outdoor furniture, allow extra travel time, and stay informed via IPMA and ANEPC updates. Yellow warnings can be upgraded to orange or red if conditions worsen.
