Magnetic storms and health of Montreuil residents: at Kp ≥ 5 weather-sensitive people may experience pressure swings, headaches, sleep issues. Especially pensioners and people with hypertension should watch the forecast. During a storm — hydrate more, avoid alcohol and strong coffee, avoid intense physical load.

Technical consequences for Montreuil at G3+: GPS, HF radio and precise positioning systems may glitch. Drivers on long routes should watch the forecast for the next 24–72 hours. Data source: NOAA Space Weather Prediction Center, refreshed every 10 minutes.

Aurora visibility threshold for Montreuil. At a geomagnetic latitude of 50.4°, the minimum Kp giving a realistic chance of visible auroras above Montreuil is about Kp ≥ 6. The current equatorial Dst index is 0 nT — the magnetosphere is in a quiet phase. Dst complements Kp by showing how long and how deep a storm's main phase has been — useful context when checking whether auroras are likely tonight.

Weather and atmospheric pressure in Montreuil right now. Temperature +17.4°C, atmospheric pressure 759.9 mm Hg (1013.1 hPa), cloud cover 0%, humidity 36%, wind 11.2 km/h. During G1+ geomagnetic storms, swings in atmospheric pressure tend to amplify symptoms for weather-sensitive people: those with hypertension often notice blood-pressure spikes, and readings below 1000 hPa combined with Kp ≥ 5 frequently bring headaches and fatigue. That is why the Montreuil page shows both indicators side by side. Weather data from Open-Meteo (CC BY).
