Spring 2015 was active from earthquakes to tornado outbreaks to an
early tropical system.
In April, the Nepal earthquake killed more than 8,800 people and
injured more than 23,000. It occurred on 25 April with a magnitude of 7.8. Its
epicenter was east of the district of Lamjung, and its hypocenter was at a
depth of approximately 9.3 miles. It was the worst natural disaster to strike
Nepal since the 1934 NepalBihar earthquake. The earthquake triggered an
avalanche on Mount Everest, killing at least 19, making April 25, 2015 the
deadliest day on the mountain in history. Hundreds of thousands of people were
made homeless with entire villages flattened, across many districts of the
country. Centuries-old buildings were destroyed in the Kathmandu
May, severe weather targeted the Plains causing major damage. The tornado
outbreak began on May 5 with isolated tornadoes in western Texas. More
widespread and significant activity occurred on May 6. Much of central Oklahoma
experienced tornadoes, and the town of Bridge Creek sustained major impacts
from a large EF2 wedge tornado, where several businesses and homes were heavily
damaged or destroyed. Another EF2 tornado caused major damage in southwestern
parts of Oklahoma City, just north of Valley Brook, where a hotel, several
self-storage units, a mobile home park, and an RV park were heavily damaged,
numerous vehicles were flipped, and at least 12 people were injured. Large,
strong tornadoes, including two EF3s, severely damaged or completely destroyed
rural homes near the Kansas towns of Mount Hope, Scandia, and Munden. Several
additional less intense tornadoes occurred on May 7 and May 8 across an area
extending from Colorado to Texas. Another wave of significant tornado activity
occurred on May 9 throughout an area extending from Nebraska to Texas. This
included a large EF3 cone tornado that caused major damage near Cisco, Texas.
Destructive tornado activity continued on May 10, as a large tornado struck the
town of Delmont, South Dakota, where severe structural damage and multiple
May 8, Subtropical Storm Ana formed in the Atlantic Ocean. Amid the warm waters
of the Gulf Stream and abnormally cold upper-level temperatures, Ana
intensified to reach peak winds of 60 mph by late on May 8, and on the
following day, the system completed its transition to a fully tropical cyclone.
Diminished by cooler waters and persistent dry air, the system moved ashore
north of Myrtle Beach, South Carolina, on May 10, with winds of 45 mph. Along
the North CarolinaSouth Carolina border, Ana produced moderate rainfall
with accumulations peaking at 6.7 in southeast of Kinston, North Carolina.
Minor street flooding took place in the city while beaches in both states
experienced 24 ft of erosion. Upon moving ashore, it became the
second-earliest cyclone to strike the United States on record, preceded only by
the 1952 Groundhog Day tropical storm.
