September 25, 2025 Thursday Evening Hurricane Season
Humberto nearing hurricane strength while Invest 94L slowly developing
September 2025 was the 7th-warmest September in the 131-year national record (1895–2025), at 67.9°F against a 1991–2020 normal of 66.0°F (+2.0°F).
September 2025 was the 15th-driest September in the 131-year national record (1895–2025), at 1.9in against a 1991–2020 normal of 2.6in (-0.6in).
NOAA/NCEI Climate at a Glance, contiguous United States. This is the observed record for the month, not a score of anything said in this piece — the forecast ledger begins 2026-08-17 and cannot reach earlier posts.
A mini-update on Humberto and Invest 94L — to keep the forecast cycles moving forward with an exhaustive newsletter Friday morning, and during the weekend. I don’t think there are any major changes or surprises with this evenings models.
We’re in a bit of a holding pattern until Invest 94L is designated as TS Imelda and that may be later this weekend.
