Weather Underground Forecast for Saturday, November 07, 2009.
Tropical storm activity will continue over the Tropical Atlantic and Caribbean on Saturday. Tropical Storm Ida will maintain its strength as it continues tracking northward and up the eastern coast of the Yucatan Peninsula. The system will continue to pour heavy showers and thunderstorms over the region due to abundant moisture fed from the Caribbean Sea. Expect tropical storm strength winds with gusts up to 73 mph and wave heights near 15 feet. Periods of intense rainfall is expected over the Yucatan with total between 1-2 inches.

The Greater Antilles may see light showers, as wet conditions develop over the Lesser Antilles due to a tropical wave moving in from the approaches the east.
On this date in 1940, Galloping Gertie Bridge in Tacoma, Wash. collapsed in high winds. It turns out the bridge spans were evenly spaced, causing the bridge to vibrate wildly with a regular frequency in high winds. Since then, bridges have been built with uneven spans.
