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.

Headline for Saturday

Invest 98L has showers and storms in a broad circulation over the central tropical Atlantic. NHC has increased development chance to 40% in the next 48-hours and 80% in the next 7-days. The main question is not if — but when 98L will become Ernesto, and then track through the Caribbean and Greater Antilles. Models are suggesting a northward turn before reaching 70°W longitude sparing the U.S. from direct impacts.
