Snowfall events in Louisiana, The states

Southeast region snow on Christmas Twenty-four hours 2004

Snow in the southern part of Louisiana presents a rare and serious problem considering of South Louisiana's subtropical climate. For snow to push into the southern region of Louisiana, extreme weather atmospheric condition for the expanse must be present, usually a low-pressure level system coupled with unusually low temperatures.^[1] Average snowfall in Louisiana is approximately 0.2 inches (5.1 mm) per year, a low effigy rivaled just by the states of Florida and Hawaii.^[2] Due to the infrequency of these common cold weather patterns,^[3] southern areas afflicted in this state are frequently unprepared to deal with slick streets and freezing temperatures.

According to the National Weather Service, measurable snow amounts occur on an average of merely once every other year in Northwest Louisiana; many sequent years may laissez passer with no measurable snow. The heaviest snowstorm of tape in the Shreveport area is eleven.0 inches (280 mm) in December of 1929. This barbarous on the 21st and 22nd, and one-one-half inch remained on the ground December 25th, making this the but Christmas Day of tape with snow on the basis. In 1948, 12.iv inches of snow was measured for the calendar month of January for the greatest monthly amount on record. Occasional ice and sleet storms do considerable damage to trees, ability and telephone lines, every bit well as make travel very hard.^[4]

Notable events [edit]

Lake Charles, Louisiana in 1895

1895: A large snow storm spanning from Texas to Alabama left New Orleans with approximately 8.2 inches (21 cm) of snow, Lake Charles with 22 inches (56 cm) of snow, and Rayne with 24 inches (61 cm) of snowfall. Nevertheless, these are unconfirmed.^[5]

1899: With the Keen Blizzard of 1899, snowfall in New Orleans reached 3.8 inches (nine.7 cm) with stiff winds and temperatures below 10 °F (−12 °C).^[5]

2000: This snowfall was nationally televised as the 2000 Independence Bowl was beingness played on December 31, 2000 in Shreveport. The game was later referred to as "The Snow Bowl", every bit a snowstorm (rare for the Shreveport surface area) began merely earlier kickoff, blanketing the field in pulverisation, and continued throughout the entire game.

2004: The 2004 Christmas Eve snowstorm swept across southern Texas and Louisiana, leaving unprecedented amounts of snow in areas that had non seen snowfall in fifteen to 120 years.^[6]

2008: It snowed in and around semi-tropical New Orleans on Thursday December 11th, 2008.

From dawn to mid-morn a thick snow of plump, moisture flakes buried much of southeast Louisiana, from Amite to Westwego, nether a coating of white. Snow superlative: Amite, LA: 8 inches (20 cm) Washington, LA: half-dozen inches (15 cm) Opelousas, LA: 6 inches (15 cm) Covington, LA: 6 inches (15 cm) Hammond, LA: 6 inches (15 cm)

2014: The early 2014 North American common cold wave that blew through the eastern portion of the continental United States produced tape low temperatures and brought freezing snowfall and sleet to Louisiana.^[7]

2017: Early in the forenoon on Dec viii, 2017, a winter storm dripped snowflakes on much of s Louisiana. Throughout the mean solar day, more and more than snow fell. Snow lasted all day long. Heavy snowfall barbarous on the ground, giving some places a height of six inches (xv cm) of snow. Most schools across Louisiana closed due to the snow.

2021: Significant snow and ice was reported nearly statewide on February 14–15, 2021 with the Feb thirteen–17, 2021 North American wintertime tempest and again on February 17 from the February xv–xx, 2021 Due north American winter storm.

State preparedness [edit]

Because of the scarcity of freezing temperatures in Louisiana, many citizens of the region are often left unprepared to handle what might exist considered a storm of little consequence in more than northern states. The region has developed a system of road and school closures with only minimal snowfall, as most drivers in the area are unprepared to bargain with slick, frozen roads.^{[8] [9]} In fact, the governor of Louisiana may cull to invoke the Louisiana Homeland Security and Emergency Assistance and Disaster Act, R.South. 29:721, to declare a state of emergency due to extreme cold and snow. In 2014, Gov. Bobby Jindal did merely that in accelerate of the weather and assembled teams to assist in preparation and recovery.^[10]

Louisiana'southward environment [edit]

The land's typically humid subtropical climate rarely encounters precipitation coupled with freezing temperatures. The Gulf of Mexico helps maintain this climate, peculiarly closer to the coast. The normally extreme summers are rarely countered by common cold winters, with snowfall depression in intensity and frequency. Also the southern portions of the country typically has two seasons, a moisture season from April to October and a dry season from November to March. The cooler season typically brings in very fiddling precipitation, likewise limiting snowfall.^[11] Average wintertime temperature normals in southern Louisiana vary from the 40s to the 60s Fahrenheit.^[3] Natural disasters such every bit hurricanes are far more than common, and such an ecosystem is sick prepared for snow, peculiarly the seafood supply on which Louisiana relies for much of its revenue.^[12] Little research has been done directly linking effects on Louisiana's ecosystem to snow conditions. Yet, the jet stream that created the 2014 North American cold moving ridge has been linked to global warming,^[13] and resultant cold fronts have been linked to salt water intrusion in Louisiana'southward Atchafalaya Bay.^[14] However, one of Louisiana's most famous animals, the alligator, has proved versatile in adapting to cold weather atmospheric condition by burrowing in "alligator holes", which they ordinarily apply for waiting out a drought.^[15] Studies conducted in Finland and Sweden suggest that snowfall creates more potential issues in urban communities due to increased pollution in runoff.^{[16] [17]} Due to the state's lack of resources and funding, however, information technology is unclear what levels of pollution due to snow affect the Louisiana area.
