⚡ Lightning doesn't just happen inside storm clouds — it can travel from the cloud to the ground at speeds up to 220,000 miles per hour. That's fast enough to circle Earth nearly 9 times in one second. But here's the twist: the return stroke (the bright flash you actually SEE) travels upward from the ground to the cloud — the opposite direction from what most people assume. Weather science is full of surprises like this. 🌩️

On this day — June 17, 2010 — four EF4 tornadoes tore through the Upper Midwest in a single afternoon. Three struck Minnesota. One hit North Dakota. Four lives were lost — the deadliest tornado day in Minnesota in over 30 years. EF4 winds reach 166–200 mph, enough to level well-built homes and throw vehicles like toys. June isn't just the start of summer. For meteorologists, it's peak storm season. Stay weather-aware. 🌩️

💧 The Amazon River discharges so much fresh water into the Atlantic Ocean that you can find fresh water on the ocean's surface up to 100 miles offshore from the river's mouth. That's not a puddle — that's a freshwater zone the size of a small country floating on top of saltwater. Our planet's freshwater systems are more powerful than most of us ever imagine. 🌊🌎
