On land:
The wind picks up dust and small pieces of paper; small branches are moved.
At Sea:
The sea is moderately rough. Waves appear in the form of elongated ridges, some of which are overturned; fairly frequent white horses.
Enhanced protection from UV radiation from the Sun is required. A UV index reading of 8 to 10 means very high risk of harm from unprotected sun exposure. Take extra precautions because unprotected skin and eyes will be damaged and can burn quickly. Minimize sun exposure between 10 a.m. and 4 p.m. If outdoors, seek shade and wear sun protective clothing, a wide-brimmed hat, and UV-blocking sunglasses. Generously apply broad spectrum SPF 30+ sunscreen every 2 hours, even on cloudy days, and after swimming or sweating. Bright surfaces, such as sand, water, and snow, will increase UV exposure.
On land:
There is a light continuous stream of wind that is felt by the face; leaves rustle; ordinary vanes moved by wind.
At Sea:
Weak and short waves in the sea, still short, but more pronounced. Crests have a glassy appearance and do not break.
On land:
The thin branches and leaves on the trees fluctuate continuously; wind extends light flag.
At Sea:
Light and short waves are clearly visible at sea. Foam of glassy appearance. Perhaps scattered white horses.
Power systems: Weak power grid fluctuations can occur.

Spacecraft operations: Minor impact on satellite operations possible.

Other systems: Migratory animals are affected at this and higher levels; aurora is commonly visible at high latitudes (northern Michigan and Maine).
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.).
