Isaias became a post-tropical cyclone as it moved into southeast Canada late Tuesday after pummeling the East Coast for much of the day with heavy rains and wind —trigging tornadoes, floods and leaving millions without power. At least six people have lost their lives in the storm.

The big picture: Isaias made landfall as a Category 1 hurricane in North Carolina late Monday before being downgraded. It dumped heavy rain across Florida as a tropical storm over the weekend. On July 31, it lashed the Bahamas and parts of Puerto Rico and the Dominican Republic as a Category 1 hurricane.

Why it matters: Satellite data is giving researchers and governments a bird's eye view of what's happening on Earth, allowing interested parties to see more than they could by just monitoring land and sea from the ground.
