Heavy downpours during the week of April 23rd in Haiti and the Dominican Republic prompted deadly floods and mudslides, affecting over 3,400 families in Haiti and more than 11,000 people in the Dominican Republic. Many of Haiti's improvised shelters are located in low-lying areas, resulting in some of them being flooded continuously, prompting concerns of sanitation risks to the population. According to reports, the copious rain claimed 16 lives across parts of southwestern and southern Haiti, with two people killed in landslides and the rest while trying to cross flood waters. Meanwhile, no fatalities or injuries were reported in the neighboring country of Dominican Republic. However, nearly 3,000 houses were damaged by the floods across northern and northeastern Dominican Republic. Torrential rain also fell across eastern Jamaica, flooding streets.

The Union of Comoros, which are islands located between northwestern Madagascar and eastern Africa, experienced torrential rains during mid-April. The heavy downpours caused severe floods and landslides, affecting over 46,000 people. According to reports, the floods damaged nearly 50 schools throughout the nation, and left three people dead and an estimated 100 people injuried.

Severe thunderstorms spawned 17 devastating tornadoes across much of northern Texas on April 3rd, 2012, wreaking havoc across the affected area. The tornadoes destroyed homes, tossed tractor-trailer trucks, and left 17 people injured. One of the hardest hit areas was the densely populated area of Dallas, where two tornadoes (one rated an EF2 tornado and the other an EF0) ripped through the area, damaging 300 structures. According to the NWS, the EF2 tornado's maximum path width was 200 yards and had a length of 7.1 miles with estimated wind speeds of 130 mph (209 km/hr). The storms also produced two inch diameter or greater size hail, damaging more than 100 planes and canceling approximately 400 flights at Dallas/Fort Worth International Airport, leaving thousands of passengers stranded.

Bouts of severe weather continued to affect parts of the contiguous United States in April 2012. Severe storms on April 13th–15th produced nearly 150 preliminary tornadoes, large hail (3 inches in diameter), and strong winds, affecting portions of the central United States. An EF1 tornado touched down in Norman, Oklahoma near the University of Oklahoma campus, causing a few minor injuries and some property damage. Meanwhile, the town of Thurman, Iowa was hit by an EF2 tornado, leaving 75 percent of the town destroyed. An EF3 tornado caused over $280 million in damages across southeastern Wichita, Kansas, leaving 90 mobile homes damaged and, according to reports, destroying a building at a Spirit Aerosystems plant. The only deadly tornado was reported in Woodward Oklahoma, where six fatalities were reported. The tornado damaged or destroyed nearly 100 homes and buildings, and brought down trees and power lines. The governors of Kansas and Oklahoma declared states of emergency.
