A watch means conditions are favourable for severe weather, so be prepared. A warning means severe weather is happening or about to happen, so act now.

Only if it is a fully enclosed building with wiring and plumbing. Small sheds and open shelters are not safe from lightning.

Check the wind chill, dress in layers, cover exposed skin, take warm-up breaks and check often for numbness or white skin.
