The cold air mass coming from Canada will cause cold weather conditions in the eastern United States in May that are as cold as those in March. Weather experts state that this cold wave will affect two-thirds of the eastern US, leading to late-season frosts. These frosts can cause damage or death to especially sensitive vegetation. Experts warn that this situation could have negative effects on the agricultural sector and daily life. The unexpected cold in May poses a significant risk for farmers and gardeners in the region.
