Walmart said it expects sales growth of 3.5% to 4.5% in the second quarter.Like many other U.S. companies, however, it did not issue a profit outlook for the quarter because of the chaotic environment, with stated U.S. tariff policies changing constantly.

ATLANTA (AP) — With new innovations and technology, scientists have learned fromover the years how to improve safety guidance. During tornado season, forecasters try to get the word out about staying safe during a storm — but also planning for it ahead of time.Tornado seasons typically begin at different times in different parts of the United States.

In what has historically been known as Tornado Alley — a designation that typically includes Kansas, Oklahoma and Texas — the peak of tornado season is May into early June. But the season starts earlier in what’s often called, made up of southern states such as Arkansas, Louisiana, Mississippi, Alabama and Georgia.

The idea of a tornado alley can be misleading, since tornadoes have been reported in all 50 states. About 1,200 tornadoes strike the U.S. every year, and each year violent twisters happen outside these traditional “alleys” of tornado outbreaks, according to the National Severe Storms Laboratory. Recent twisters have even struck in places unaccustomed to them, such as

in 2023 that tore apart rooftops and injured one person.Without intervention, scientists like Van Damme warn these trees could disappear within a few centuries — and with them many other species.
