You can see 5-day forecasts for tropical storms and hurricanes by accessing the National Hurricane Center site. Google it up. It will give you a complete assessment of the chances of the tropical storm increasing or dissipating, based on meteorological measurements and aircraft assessments. At present, TS Chris is at 40 mph max wind strength, with very unfavorable conditions, in fact expected to dissipate because of windshear. Keep in mind that tropical storms are NOT hurricanes, just a good rain in most cases. The main concern about the TS is potential beach erosion because of high surf, and you would want to stay out of the Gulf waters because of rip tide conditions. If it was my vacation, I would certainly not curtail it on the basis of a tropical storm, especially one with this kind of forecast.
When you access the Web site, click on the "maps" and look at the 5-day forecast. You may also want to read the advisory text, which will tell you whether meteorlogocial conditions favor strengthening or dissipation. This information is now pretty accurate. Go and enjoy!
