Weather Underground
My favorite online resource for weather is Weather Underground. It is packed full of information, and displays weather stats from thousands of spots in the country. They have a terrific tropical storm section, too. When a hurricane forms, every last detail about the storm is on Weather Underground.
The site is indeed a little cluttered with all of the ads and tables of information, but you can access so many resources that you can become your own expert. The site offers up code that you can include on your own website to display the weather stats. During my last visit, I found they have integrated the local temperature and reading stations with Google Maps. See the screenshot, below. I think it is so awesome.
