subtropical climate. For snow to push into the southern region of Louisiana, extreme weather conditions for the area must be present, usually a low-pressure system coupled with unusually low temperatures.[1] Average snowfall in Louisiana is approximately 0.2 inches (5.1 mm) per year, a low figure rivaled only by the states of Florida and Hawaii.[2] Due to the infrequency of these cold weather patterns,[3]
southern areas affected in this state are often unprepared to deal with slick streets and freezing temperatures.

According to the National Weather Service, measurable snowfall amounts occur on an average of only once every other year in Northwest Louisiana; many consecutive years may pass with no measurable snowfall. The heaviest snowstorm of record in the

Shreveport area is 11.0 inches (280 mm) in December 1929. This fell on December 21 and 22; half an inch remained on the ground on December 25 making this the only Christmas Day of record with snow on the ground. In 1948, 12.4 inches of snow was measured for the month of January for the greatest monthly amount on record. Occasional ice and sleet storms do considerable damage to trees, power and telephone lines, as well as make travel very difficult.[4]

Notable events

Lake Charles snow in 1895.
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 snow. However, these are unconfirmed.[5]

1899: With the Great Blizzard of 1899, snowfall in New Orleans reached 3.8 inches (9.7 cm) with strong winds and temperatures below 10 °F (−12 °C).[5]

2000: This snow was nationally televised as the

Shreveport
. The game was later referred to as "The Snow Bowl", as a snowstorm (rare for the Shreveport area) began just before kickoff, blanketing the field in powder, 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 not seen snow in 15 to 120 years.[6]

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

From dawn to mid-morning a thick snowfall of plump, wet flakes buried much of southeast Louisiana, from Amite to Westwego, under a blanket of white. Snow height: Amite, LA: 8 inches (20 cm) Washington, LA: 6 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 cold wave that blew through the eastern portion of the continental United States produced record low temperatures and brought freezing snow and sleet to Louisiana.[7]

2017: Early in the morning on December 8, 2017, a winter storm dripped snowflakes on much of south Louisiana. Throughout the day, more and more snow fell. Snow lasted all day long. Heavy snowfall fell on the ground, giving some places a height of 6 inches (15 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

State preparedness

Because of the scarcity of freezing temperatures in Louisiana, many citizens of the region are often left unprepared to handle what might be considered a storm of little consequence in more 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 deal with slick, frozen roads.[8][9] In 2014, Gov. Bobby Jindal invoked the Louisiana Homeland Security and Emergency Assistance and Disaster Act in advance of the weather and assembled teams to assist in preparation and recovery.[10]

Louisiana's environment

The state's typically

Atchafalaya Bay.[15] However, one of Louisiana's most famous animals, the alligator, has proved versatile in adapting to cold weather conditions by burrowing in "alligator holes", which they usually use for waiting out a drought.[16] Studies conducted in Finland and Sweden suggest that snow creates more potential problems in urban communities due to increased pollution in runoff.[17][18]
Due to the state's lack of resources and funding, however, it is unclear what levels of pollution due to snow affect the Louisiana area.
