NOAA also aims to expand its flood inundation mapping (FIM) tool—which provides real-time, street-level visualizations of flood waters—to cover 60% of the U.S. this year.

NOAA is predicting between 13 and 19 named storms in 2025, making it an above-average season.

During El Niño, winds over the Atlantic high up in the troposphere – roughly 25,000 to 40,000 feet – strengthen and can disrupt storms and hurricanes.
