Hurricane Lee winds and waves to impact Northeast US this weekend

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 Lee looked great on satellite Sunday evening with a clear eye surrounded by deep convection. And, then it all went sideways for Lee, again. Dry air and wind shear seems to cause Lee to sputter after it intensifies or spins up. Central pressure remains around 948 mb consistent with a major hurricane [ 105-knots ] but certainty not Category 4 or 5.
