How do buoys detect hurricanes?

The drifting buoys, called drifters, collect data on sea surface temperature, wind, and atmospheric pressure, and transmit this data in real-time via the Global Telecommunication System. This data provides important information that can help forecasters predict the path and intensity of hurricanes.

What is the general rule when anchoring in calm waters?

To anchor safely: Lower the anchor to the bottom and let the vessel travel backwards until enough line is let out. Allow 3 times as much line as the depth of water. If the weather deteriorates, or in strong currents, increase the line to depth ratio to 5:1 or more.
