🔍 Key Concepts

• Tropical cyclone swell patterns and how they travel away from the storm center • Typical barometric pressure behavior as a cyclone approaches (near vs far) • Local wind shifts and rain patterns when a storm is already nearby or passing

💭 Think About

• Which sign would logically be detectable first when a tropical cyclone is still several hundred miles away, before strong winds and heavy rain arrive? • Does a barometer usually show a smooth trend or rapid up‑and‑down "pumping" when the storm center is still far away? • Are sudden wind shifts and strong, increasing winds more likely when the storm is close by, or still 500–1,000 miles distant?

✅ Before You Answer

• Match each option to the likely distance of the storm: very far away, several hundred miles, or already near/passing • Consider the time scale on which swells, pressure changes, and wind shifts are felt relative to the storm’s approach • Ask: which sign could affect your area well before the main storm circulation and bad weather arrive?
