Tropical storms form in both Atlantic and Pacific oceans
Tropical storms formed in both the Atlantic and Pacific oceans on Sunday, with one having the potential to turn into a hurricane.
Tropical Storm Fay formed in the Atlantic on Sunday, while Tropical Storm Odalys formed in the Pacific.
Fay is currently centered more than 400 miles southwest of the Azores and is moving northeast at 3 mph.
Odalys is located in open water more than 1,300 miles southwest of the southern tip of Baja California and is moving west-northwest at 9 mph.
Odalys, which is packing maximum sustained winds of 45 mph, is forecast to gradually strengthen into a Category 1 hurricane by late Monday.
Neither Odalys nor Fay will threaten land.
In addition to Odalys, two tropical disturbances in the central and eastern Pacific are also being monitored.
Fay becomes the sixth named storm of the 2026 Atlantic hurricane season, though comparatively tardy. The sixth named storm of the Atlantic hurricane season typically forms around August 29, making Fay about three weeks later than average.
Fay is also the first named storm in the Atlantic since Edouard formed on August 31.
Heat wave continues in parts of the South and Midwest
A widespread record-breaking September heatwave continues for one more day in parts of South and the Midwest.
High temperatures in some areas are expected to peak in the upper 90s to near 100 degrees and challenge daily records.
Heat advisories are in effect on Sunday afternoon from Illinois down to Tennessee, including Evansville, Indiana; Bowling Green, Kentucky; Nashville, Tennessee; and Poplar Bluff, Missouri.
Daily high-temperature records are being threatened in some cities on Sunday, including Evansville, Indiana and Memphis, Tennessee.
On Saturday, 17 cities broke or tied daily high-temperature records, including Jonesboro, Arkansas, which hit 103 degrees, and Salina, Kansas, which reached 101.
Memphis and Nashville, Tennessee; Tuscaloosa, Alabama; Greenville, Mississippi; and Fort Smith, Arkansas, all hit the century mark on Saturday, breaking daily high-temperature records.
However, a cooling trend on the way could finally put an end to the September heatwave. By Tuesday, highs will be about 20 degrees cooler in cities like Evansville, with afternoon temperatures peaking in the upper 70s.
Flash-flood threat continues in the Midwest and Rockies
The threat of flash flooding in the Midwest and Rockies is expected to continue on Sunday afternoon. Heavy rains fell over swaths of southern Montana, as well as in the Midwest from southern Minnesota down to northern Illinois.
A widespread 2-plus inches of rain fell from Cedar Rapids, Iowa, to Aurora, Illinois, early Sunday, with some local weather stations reporting upward of 3 to 4 inches, producing some instances of creeks rising and roads flooding.
Flood watches remain in effect Sunday afternoon for parts of eastern Indiana, Ohio, West Virginia and southwestern Pennsylvania.
More heavy rain is likely on Sunday from east-central Missouri to southwest Pennsylvania and West Virginia. A widespread 1 to 2 inches of precipitation is possible in this area, with local heavier downpours possibly bringing 2 to 5 inches of rain.
On Monday, the flash-flood threat is lower, but locally heavy downpours are possible for parts of the Mid-Atlantic later in the day.
