Fact # 3
Fact #2

Fact # 4
Fact #3

7. Temperature – Louisiana has two extremes and both were recorded in north Louisiana.
The record cold was -15 at Minden in Webster parish (2/15/1899). The record high was 114 at Plain Dealing in Bossier parish (8/10/1936).
The towns were less than 50 miles apart.
Fact #4

8. Precipitation – means any form of water – rain, sleet, hail, snow – liquid or solid. You tend to get more in southern Louisiana and less in northern Louisiana.
Fact #5

9. Tornadoes – give very little warning and develop in less than 5 to 10 minutes. Radar can spot tornadoes but not in time to warn people.
Tornado wind speeds can reach as much as 300 mph and have a destructive path as wide as a football field.
Fact #6

10. Fajita Scale – Tornadoes use a Fajita scale of intensity from F-0 (40-72mph) up to a F-5 ( mph)
Louisiana ranks in the top 12 states that are hit by tornadoes each year.
Fact #7

11. Hurricane – begins over tropical waters and rotate around a calm center. Radar can generally predict landfall to with a few hours. Even though they cover more land than tornadoes, people have time to prepare and move from their path.
Fact #8

12. Saffir-Simpson – Hurricanes are rated on a SS Scale of 1-5
Saffir-Simpson – Hurricanes are rated on a SS Scale of 1-5. Category 1 (74-95mph) to Cat 5 (over 155). More than 60 hurricanes have hit Louisiana since 1850 but it will be the two that struck in 2005 that will be long remembered – Katrina and Rita.
Fact #9

13. Climate and Agriculture – Our climate helps with a longer growing season nearly 200 days - more moist days, more sunlight, less chance for frost but sometimes the unexpected happens like hurricanes, tornadoes, early frost.
