Wind: near gale, western, speed 50 km/h Wind gusts:68 km/h Relative humidity: 77% Atmospheric pressure: 989 hPa Waves in the sea:phenomenal, wave height of 4 m Visibility: 65% Water temperature in the sea: +4 °C Geomagnetic Field:Moderate Storm
Large branches bend on the trees, and the trunks sway; inconvenience felt when walking against the wind.
At Sea:
Strong waves are piling up on the sea; Sea heaps up and white foam from breaking waves begins to be blown in streaks along the direction of the wind.
Power systems: High-latitude power systems may experience voltage alarms,
long-duration storms may cause transformer damage.
Spacecraft operations: Corrective actions to orientation may be required by ground control;
possible changes in drag affect orbit predictions.
Other systems: HF radio propagation can fade at higher latitudes,
and aurora has been seen as low as New York and Idaho (typically 55° geomagnetic latitude.).
