The report reveals that no fewer than seven outbreaks of severe convective storms swept across central and eastern sections of the United States. Preliminary local storm report (LSR) data from NOAA indicates that there were nearly 4,400 individual reports of tornadoes, hail, and straight-line winds – the most in May since 2011.
In addition to the thunderstorm impacts was continued flooding, as record-breaking rainfall in Oklahoma and Kansas resulted in historic flooding throughout the Arkansas River Basin, accompanied by remnant flooding in the Missouri and Mississippi River Basins. Total economic and insured losses from the convective storm and flood impacts were each anticipated to reach into the billions of dollars (USD).
Steve Bowen, Director and Meteorologist within Aon’s Impact Forecasting team, said: “Historically, May has been the most active month for tornadoes in the United States and 2019 was no exception, with the highest May tally since 2015. A persistent weather pattern led to several multi-day outbreaks of severe weather that resulted in tornadoes, large hail, damaging straight-line winds, and record-breaking rainfall which had a considerable impact on property and the agricultural sector. Severe convective storms have resulted in at least USD10 billion in U.S. insurance payouts annually since 2008, and we are likely headed towards a 12th consecutive year.”
Other natural catastrophe events to have occurred elsewhere during May include:
• Ongoing drought conditions in China’s Yunnan Province affected more than 273,000 hectares (675,000 acres) of cropland at a financial cost of CNY953 million (USD138 million).
• Prolonged rainfall impacted much of Paraguay, leading to widespread flooding that killed at least six people, led to the evacuation of over 40,000 residents, and caused significant harm to the cattle industry.
• An outbreak of severe weather impacted portions of Southern Europe, with abundant rainfall causing an overflow of rivers in the Emilia-Romagna region and inundating around 600 homes and businesses, and adjacent agricultural land. The same weather system also affected the Balkans.
• The Arabian Peninsula endured heavy rainfall, prompting flooding that was exacerbated by poor infrastructure. Six people were killed in Yemen alone, including in parts of Sanaa, while at least six people went missing after being swept away by flash flooding in the Wadi Bani Khalid in Oman. One person was swept away by floodwaters in Saudi Arabia. Total economic costs were forecast as millions (USD).
• Heavy rainfall resulted in localized flooding in Tanzania, with Dar es Salaam and the Mbeya region hardest hit. Five people died, thousands were displaced, and more than 1,000 homes were flooded.
