Sign in to your Twitter account or get a new account for free. If you do not wish to interact with other users on Twitter, follow the directions provided here after you have registered with Twitter. Tip: Look for the option to "Skip this step" near the bottom of virtually every page during the Twitter signup process.

Select your location from the drop down menu that appears when you click here. Then you simply click on the follow button in the upper left corner of the page. You can repeat this step as often as you wish. If you cannot find your desired city, full state feeds for all fifty states are available on this menu.

If you wish to have the alerts directed to your phone via SMS, click here and enter your phone number with area code and confirm that your country is set to United States. Once finished, be sure to click on the phone icon on the profile page of the location you have chosen to follow to fully activate the alerts.

If you only need applications for your phone click here. If you will be receiving your alerts via any computer you will first need to download and install Adobe Air. We recommend downloading either TweetDeck or Seesmic Desktop next. You can also use the Twitter web interface by signing into your account.

For phones using the Android operating system (including the Nexus and Droid) you can use either TwiDroid or Seesimic. For the iPhone you can use either Twitteriffic or Echofon. For BlackBerrys you can use TwitterBerry or TweetCaster. For all other phones, select from the available options here.
