Looking at data from the SREF, or Short Range Ensemble Forecast from the SPC (Storm Prediction Center), it appears that the main window for severe weather in Alabama will be from 10 a.m. through 10 p.m., Saturday April 27, 2010. However, a few storms could be severe before or after that time. Also, there may be a lull in the action some of that time.

Parameters seem to be coming together favorably for the possibility of large tornadoes between 4 p.m. and 7 p.m. in West, North, and Central Alabama.

Having said the above, the best thing to do with this powerful and complex developing weather system is watch the weather closely as it develops throughout the day.

• All outdoor events should be canceled.
• All Alabamians should be close to a good source of weather information, including local media and NOAA Weather Radio. Please do not depend on sirens.
• Every family should have a plan in the event a warning is issued for your area.
• Every warning should be taken with a heightened level of seriousness.
• If you see a storm in your area, assume that it could produce a tornado and take cover immediately.
• Avoid mobile homes and driving cars as much as possible in areas with storms. Most people die in mobile homes and cars during tornadoes.
• Basements and storm shelters provide the best protection. Otherwise, seek shelter on the lowest level of a building, near the middle, preferably a small room such as a closet, and stay away from windows.
• Take personal responsibility for the safety of you and your family.
• Stay calm, but remain alert to weather all day and night.
• Let's make it a goal that regardless of the weather, residents of Alabama experience no serious injuries or death on Saturday.
