☁️ NOAA NCEI is moving to the cloud! Over the next 10 months, all of our data, products, and services will migrate from physical servers located in Asheville, NC and Boulder, CO to the Amazon Web Services (AWS) Cloud.
.
🖥️ For more information on the cloud migration and how it will affect the services provided by NCEI, read our web story at the link in our bio.
Check out NCEI’s Global Temperature and Precipitation Analysis for April. Here are the highlights:
🌍 April was the fourth-warmest April on record.
🌎 The Northern Hemisphere had a below-average snow cover extent, driven by deficits in Eurasia.
🌏 Both poles experienced below-average sea ice extent, with the Arctic having its second-smallest April extent on record.
🌍 Global tropical cyclone activity was near average with four named storms.

Did April showers bring May flowers? For much of the U.S., the answer is “it depends.”
Good thing we have the April U.S. temperature and precipitation report ready. Some highlights:
➡️ The U.S. experienced its third-warmest April on record, with record-warm average temperatures observed across more than 700 counties and affecting more than 50 million people.
➡️ The last 12 months (May 2025–April 2026) were warmer than any other 12-month period on record for the CONUS.
➡️ The Upper Midwest region experienced its wettest April on record, receiving approximately twice its average precipitation.
➡️ Severe to exceptional drought covered over 40% of the U.S., with the Southeast experiencing its greatest extent on record.

🌪️The updated Advanced Dvorak Technique-Hurricane Satellite (ADT-HURSAT) dataset is here! Created by @noaa and #CIMSS at @uwmadison , ADT-HURSAT provides reliable hurricane intensity records for 1978 through 2024. These reliable long-term records help communities, businesses, and scientists understand how storms develop and how risks change over time.
.
🌧️As the 2026 hurricane season approaches, this historical data can improve risk analysis and storm preparedness to enhance #PublicSafety and help businesses protect supply chains to ensure essential goods are available.
.
🌀NOAA environmental products like ADT-HURSAT help businesses and communities plan ahead, reduce storm impacts, and protect lives, property, and local economies. Learn more about ADT-Hursat at the link in our bio.
The U.S. and Texas are entering peak hail season! Storm Prediction Center data tells us that Texas has led the nation in hail reports for the last decade. It isn’t every day that Texans see a record-breaking hailstone, though.
On June 2, 2024, a supercell thunderstorm developed in Swisher County, Texas. A large hailstone was discovered beside the road by storm chasers who were tracking the storm. A committee of scientists have verified a new Texas hailstone record of 7.1 inches in diameter.

💧 NCEI is excited to announce our new and improved Marine Microplastics portal! The portal serves as a go-to point for providing streamlined access to NCEI’s comprehensive marine microplastics data archive.
.
💻 The portal features a GIS interactive map displaying aggregated data of microplastic concentration from various marine settings/environments. Users can also find instructions on how to download and submit microplastic data, general information on microplastics and education and outreach materials.
.
🔬 Did you know that marine microplastics are less than 5 mm in size? Visit and explore the new portal to learn more about microplastics and explore the different tools available for studying their impact at the link in our bio.
🌊 Happy Earth Day! NOAA's National Centers for Environmental Information (NCEI) is excited to announce the recent upgrade of the Bathymetric Data Map Viewer. The upgrade will provide increased performance and responsiveness, better mobile usability, more powerful search/filtering capabilities, and improved accessibility for users.
.
🌎Bathymetric data is the mapping of underwater terrain and measurement of water depth. This information is crucial to successful maritime navigation, understanding deep-sea marine life and monitoring changing coastlines. Celebrate Earth Day by learning more about the importance of bathymetric data and exploring the viewer at the link in our bio. #earthdaynoaa
Check out NCEI’s Global Temperature and Precipitation Analysis for March. Here are the highlights:
.
🌍 With temperatures above average across much of the globe, March 2026 tied as the second-warmest March on record.
.
🌎 The Northern Hemisphere experienced its sixth-lowest March snow cover extent.
.
🌏 The Arctic experienced near-record-low March sea ice extent, while the Antarctic had a below-average extent.
.
🌍 In March, six named storms formed globally, which is near-average activity.

NCEI is here with the Monthly Temperature and Precipitation Report for March 2026. In honor of #NationalAllIsOursDay, share the latest information from the March report widely amongst your colleagues and friends.
▶️ Warmest March: The contiguous U.S. (CONUS) average temperature was 9.4°F above the 20th-century average, making March 2026 the warmest March in the 132-year record.
▶️ Prolonged warmth: The April 2025–March 2026 period now stands as the warmest 12-month span ever recorded for the CONUS (since 1895).
▶️ Record daily heat: 1,432 counties—over half the CONUS area and one-third of the population—observed their single warmest March day on record (1950–present).
▶️ Record-dry year to date: The January–March period was the driest on record for the CONUS—less than 70% of average—breaking the previous record set in 1910.
▶️ Notable drought footprint: Dry conditions expanded drought to nearly 60 percent of the CONUS—the largest extent of drought since November 2022.
▶️ Cold in Alaska: Alaska had its fourth-coldest March on record (since 1925) and the coldest since 2007.

From February 22–23, 2026, a powerful low-pressure system off the coast of New England moved northeast over the Atlantic Ocean. Intense snowbands developed over a swath of Rhode Island, producing snowfall rates that reached at least four inches per hour.
A committee of scientists have verified a new Rhode Island 24-hour snowfall record from the event—37.9 inches.

The Coastal Relief Model (CRM) for the Pacific Northwest Region just received its first major update in 22 years!
.
The most noticeable upgrade to the CRM is the improvements made to its resolution. The model now offers nine times the detail of the region’s topography and bathymetry compared to the previous version.
.
While the Pacific Northwest has been relatively unaffected by natural hazards, no place on earth is safe from natural disaster. This upgrade reflects an effort to increase preparation for flooding in the region from tsunamis, storm surges and more.
.
This #TsunamiAwarenessWeek, learn more about the Pacific Northwest’s CRM and how it helps the region at the link in our bio.
