What is the 'Surada' (Viento Sur / Suroeste) along the central and northern coast of Chile, and what sea conditions does it typically generate for small craft in the afternoon?

1. A strong, persistent South to South-Southwest wind driven by the South Pacific Subtropical High; it typically strengthens in the afternoon, creating steep, short, choppy seas and coastal wind waves
2. A gentle warm breeze blowing from the high Andes mountains toward the ocean at midnight
3. A dense tropical rainstorm accompanied by continuous lightning that occurs only in midwinter
4. A sudden westerly squall caused by volcanic eruptions in Patagonia
