Fact # 2
Fact #1
Weather –is often confused with the word “climate” but
they are not the same. Weather is a look at the current
conditions – temperature,
precipitation, and wind.
Fact # 3
Fact #2
Climate – is the average of weather over an area during a long span. The weatherman does not give a climate report.
Fact # 4Humid Subtropical – Louisiana has the same
weather as areas near the equator yet we had
some cold snaps which give us our subtropical
status.
Fact #3
Fact #4
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.
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
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
Fajita Scale – Tornadoes use a Fajita scale of intensity from F-0 (40-72mph) up to a F-5 (261-318mph)
Louisiana ranks in the top 12 states that are hit by tornadoes each year.
Fact #7
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
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
