Dallas Tornadoes and Flooding — Extreme Weather in Dallas
Situated in Tornado Alley (the area of the country that is most prone to tornadoes), Dallas is no stranger to extreme weather. As part of the severe storms that the area experiences, flooding has also been an issue in the city.
In the late 1800s and early 1900s, flooding along the Trinity River led to several historic weather events. In May of 1908, the river experienced extreme flooding that caused an estimated $2.5 million in damages. More recently, Dallas received a record-breaking 16.96 inches of rain in May 2015.
Tornadoes have also caused extensive damage to various locales around the city. One of the most powerful tornadoes to have ever hit the area was an EF-4 (near Garland) in 2015. This extremely strong tornado was part of a rare winter storm that caused a full-blown tornado outbreak. On multiple occasions, Dallas has also experienced strong EF-3 tornadoes (most recently in 2019).
Although powerful tornadoes are relatively rare in Dallas, there are plenty of EF-0 through EF-2 tornadoes that sweep through the area. Because of the frequency of tornadoes in the city, it is important for all locals to establish places to take shelter in the likely event of severe weather. Since the weather can stay mild through the winter months, it is important to practice tornado drills throughout the year.
