April brought widespread rainfall and severe storms to the central U.S., and much of the West, South and East remained dry and unseasonably warm
Key Points:
- A slow-moving storm system in early April brought widespread flooding and over 150 tornadoes to the South and Midwest, resulting in numerous injuries and at least 24 fatalities.
- April temperatures were particularly warm across the Southeast and Mid-Atlantic, with near-record warmth observed in the Carolinas and neighboring states.
- Alaska had its second-wettest April on record and its fourth-warmest year to date.
- Heavy rain in Puerto Rico in late April triggered flash flooding and landslides.
Other Highlights:
Temperature
The average temperature for the contiguous U.S. (CONUS) in April was 53.6°F, which is 2.6°F above the long-term average and ranks in the warmest third of the 131-year record. April temperatures were above average across much of the Lower 48, with much-above-average warmth observed across the South and Atlantic coastal regions. North Carolina and Virginia observed their second-warmest average April temperatures on record, with South Carolina and Georgia recording their third- and fourth-warmest (tied), respectively. For the year to date, the CONUS average temperature was 41.1°F, 2.0°F above average, ranking in the warmest third of the record for this January–April period.
The Alaska statewide April temperature was 27.5°F, 4.2°F above the long-term average, ranking in the warmest third of the 101-year period of record. While temperatures were near average across much of western Alaska in April, above-average warmth dominated the eastern part of the state. Alaska’s January–April average temperature was 17.8°F, 7.5°F above the long-term average, ranking as the fourth warmest on record, with much of the state experiencing much-above-average temperatures during this period.
Hawai’i had an average temperature of 65.9°F in April, 1.1°F above the 1991–2020 average and ranking in the warmest third of the 35-year record. Hawai’i had its second-warmest (tied) January–April average temperature of 64.8°F, 1.1°F above the 1991–2020 average for this period.
Precipitation
April precipitation for the CONUS was 2.82 inches, 0.30 inch above average, ranking in the upper third of the historical record. Drier-than-average conditions were observed from the West to the central Rockies, and along parts of the Gulf and Atlantic coastal regions. Conversely, above-average precipitation fell across a broad area stretching from the southern Plains through the middle Mississippi Valley into the Ohio Valley and lower Great Lakes, as well as in portions of the northern Plains, upper Mississippi Valley and far Northeast. Kentucky recorded its second-highest average rainfall for the month of April, while Oklahoma and Missouri saw their third- and fourth-wettest Aprils, respectively. The January–April precipitation total for the CONUS was 8.77 inches, 0.70 inch below average, ranking in the driest third of the record for this period.
Alaska’s average precipitation in April ranked as the second wettest in the 101-year record, with particularly wet conditions along the Gulf of Alaska coast and the northern Southeast region. Near-record-high snowfall was observed at the Alyeska (36.6 inches) and Denali National Park (26.5 inches) stations—these totals were the second-highest on record for April. The January–April precipitation total for Alaska was 10.97 inches, 1.80 inches above average, ranking in the wettest third on record for the period
Precipitation averaged across Hawai’i in April totaled 4.11 inches, 0.90 inch below average, ranking in the middle third of the 1991–2025 record. Drier-than-average conditions were mostly observed on the eastern portions of Moloka’i, Maui and the Big Island, while most other areas experienced above-average rainfall. Precipitation across Hawai’i for January–April was 15.65 inches, 6.42 inches below average, ranking in the driest third of the 1991–2025 record.
Drought
According to the April 29 U.S. Drought Monitor report, approximately 37.0% of the contiguous U.S. was in drought, down about 6.4% from the beginning of the month. Drought conditions expanded or intensified across parts of the Southwest, southern Rockies, northern High Plains, Florida and Hawai’i. Meanwhile, drought contracted or was reduced in intensity across much of the central U.S., parts of southern Appalachia and the Great Lakes region.
Monthly Outlook
Much of the country is expected to be warmer than average in May, from the Rockies eastward to the Atlantic and southward to the Gulf Coast. Above-average precipitation is favored in parts of the West and Rockies, and is likely across the southern Plains, while drier-than-average conditions are expected in the upper Mississippi Valley and Great Lakes region.
Drought conditions in May are likely to persist across the Southwest and northern Plains, with some improvement in the central Great Basin. Portions of the southern and central Plains should see some drought improvement and areas of removal, but the upper Mississippi Valley can expect some areas of drought development. Drought will likely persist and expand across the Carolinas and western Virginia; conditions in some areas further northeast are expected to improve.

Significant wildland fire potential for May is above normal for parts of the Southwest and upper Mississippi Valley, and from the Mid-Atlantic coastal regions down to Florida.
