A train was derailed in Warren County, Illinois, as severe storms brought winds of up to 161 km/h (100 mph) across the region on June 17, with National Weather Service surveys confirming three EF-1 tornadoes in Illinois and Iowa.
The Storm Prediction Center (SPC) has placed portions of the Central Plains including parts of Kansas and Nebraska under an Enhanced Risk of severe thunderstorms for Saturday, June 20, 2026. Large to very large hail, damaging winds exceeding 121 km/h (75 mph), and tornadoes possible from afternoon into evening hours.
One person died as flooding linked to the remnants of Tropical Storm Arthur prompted water rescues, evacuations, and road closures across parts of Mississippi and Louisiana on June 18, 2026. A dam in the Swan Lake in northern Harrison County was damaged in Mississippi while up to 610 mm (24 inches) of rain fell in parts of Louisiana.
A 40-year record of solar observations has revealed that structural changes linked to the Sun’s 11-year activity cycle are becoming increasingly concentrated near the solar surface. The finding is based on helioseismic measurements spanning Solar Cycles 22 through 25 and offers a new view of how solar magnetic activity evolves beneath the visible surface.
Multiple reported tornadoes affected parts of the Midwest on June 17, 2026, causing widespread damage in Illinois. At least one person was injured in Coles County after a reported tornado touched down near Mattoon. Severe damage and gas leaks were reported in Effingham, while a Local State of Emergency was declared for Charleston due to the storm damage.
Two teenage girls died and a 40-year-old woman remained missing as of June 17, 2026 after four members of the same family became trapped by rising water near the dam at Springfield Lake in Missouri at 16:30 LT on June 14. A 12-year-old was rescued shortly after the incident, while search operations involving more than 40 responders continued for the missing woman.
Tropical Storm Arthur formed about 100 km (60 miles) east-northeast of Port O’Connor, Texas on June 17, 2026 and is forecast to move northeastward along the Gulf Coast before tracking inland over southwestern Louisiana.
A Moderate Risk (Level 4 of 5) for severe thunderstorms has been issued for parts of Indiana and Illinois through June 17, 2026. Wind gusts of over 120 km/h (75 mph), damaging hail and multiple tornadoes are forecast across the region as the storm system moves through the Midwest.
Heavy rainfall, flash flooding, storm surge, and isolated tornadoes are expected across portions of the Gulf Coast as Potential Tropical Cyclone One tracks along the Texas coast on June 17, 2026. While the system is unlikely to develop into a tropical cyclone, it could bring rainfall totals of up to 500 mm (20 inches) to some areas along with the severe weather.
PHIVOLCS reported that the M7.8 earthquake off southern Mindanao, which caused dozens of fatalities and widespread damage, raised sections of the coastline in Sarangani and Davao Occidental provinces by as much as 2 m (6.6 feet). Authorities and environmental teams observed shoreline expansion reaching up to 200 m (656 feet) in some locations, exposing coral reefs and marine ecosystems that had previously remained underwater.
