Real-time coverage of severeStorms event — Spain Severe Weather Alert — MeteoAlarm — Pandita Data.
⛈️ OPEN LIVE 3D WEATHER ALERTSA severe thunderstorm system is affecting central Spain on 18 May 2026, with MeteoAlarm issuing widespread alerts across the Madrid region (40.4°N, 3.7°W) and surrounding provinces. Forecasters warn of damaging wind gusts exceeding 70 km/h, torrential rainfall rates of 40–60 mm/h, and frequent lightning strikes. Emergency services have activated protocols for flash flooding in urban drainage systems and exposed hillsides where soil saturation is already elevated from spring precipitation. The system is expected to peak in intensity through the afternoon and early evening hours.
This storm develops from the collision of warm, moist air masses from the Mediterranean with a cold upper-level trough pushing southwestward from the Atlantic. As warm air is forced upward, it undergoes rapid convective instability—water vapour condenses violently, releasing latent heat and driving powerful updrafts and downdrafts. The wind shear (change in wind speed and direction with altitude) tilts the storm, allowing it to maintain structure and intensify hail production and downdraft-driven straight-line winds called derechos.
Real-time satellite imagery from NOAA GOES-16 and Copernicus Sentinel-5P detects cloud-top brightness temperatures (−70°C minimum), a hallmark of strong updrafts. Weather radars operated by Spain's Agencia Estatal de Meteorología (AEMET) map reflectivity cores (40–50 dBZ) and vertical motion, while surface stations log wind gusts and precipitation accumulation every 10 minutes.
Central Spain's topography—the Sierra de Guadarrama foothills—can intensify orographic lift, concentrating rainfall. Urban areas like Madrid (population 3.3M) face flash-flood risk in subway systems and low-lying neighbourhoods. Lightning fatality risk peaks in rural zones with limited shelter infrastructure.
Track this developing system in real time using Pandita Data's interactive weather simulation, powered by NOAA and AEMET data feeds. Monitor radar reflectivity, wind vectors, and rainfall accumulation across the Iberian Peninsula to stay ahead of the hazard.
