Sept 12, 2024 Francine Drenches Southeast

Gordon expected to be a fish storm, potentially a major hurricane

What the month did

September 2024 was the 2nd-warmest September in the 131-year national record (1895–2025), at 68.6°F against a 1991–2020 normal of 66.0°F (+2.7°F).

September 2024 was the 44th-driest September in the 131-year national record (1895–2025), at 2.3in against a 1991–2020 normal of 2.6in (-0.3in).

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.

Hurricane Francine made landfall on Wednesday as a Category 2 (100 mph) in line with model and statistical forecasts. HAFS mesoscale models picked up on the burst of convection and deepening into the low-970s pressure. NHC nailed the landfall intensity.

Francine was baked in the cake > 1 week prior with A.I. model guidance showing the development and track up to 10-days in advance. The predictability of tropical storm formation seems much higher with circulation induced systems like Francine that are a product of large-scale patterns rather than convective whims of the monsoon trough.
