The federal income tax is a pay-as-you-go tax. You must pay the tax as you earn or receive income during the year. An employee usually has income tax withheld from his or her pay. If you do not pay your tax through withholding, or do not pay enough tax that way, you might have to pay estimated tax.
Locals say the swirling winds twisted ore into what we now call the Tennessee Tornado. A force of nature all its own, this triple spiral-looping coaster makes you feel like you've landed inside a funnel cloud as you zoom down a 128-foot drop through an actual mountain at speeds nearing 70 mph. It's enough to make local weather forecasters issue a Tennessee Tornado Warning!.
The only evidence indicating the wind speeds found in the tornado was the damage left behind by tornadoes which struck populated areas. Some believed they reach 400 mph (640 km/h); others thought they might exceed 500 mph (800 km/h), and perhaps even be supersonic.
