Unexpected Lake Formation in Death Valley | 23 Feb 2024
North America’s driest region, Badwater Basin, nestled within Death Valley has experienced a significant increase in precipitation since August 2023, leading to the unexpected formation of Manly Lake.
- Manly Lake was formed after Hurricane Hilary in August 2023. While it initially got smaller as expected, it surprisingly stayed throughout the fall and winters.
- It grew again in February 2024 because a strong atmospheric river brought more water.
- An atmospheric river is a narrow band of concentrated moisture in the atmosphere that carries water vapour from the tropics to higher latitudes.
- Unlike a visible water body, an atmospheric river is an invisible, elongated corridor in the sky that carries large amounts of water vapour, influencing weather patterns and precipitation.
- This disrupted the basin's usual pattern of rapid evaporation, allowing the unexpected formation and persistence of Manly Lake.
- It grew again in February 2024 because a strong atmospheric river brought more water.
