1-minute Mesoscale Domain Sector GOES-16 (GOES-East) “Clean” Infrared Window (10.3 µm) images (above) showed Atlantic Tropical Depression Three as it intensified to become Tropical Storm Bret at 2100 UTC on 19 June 2023. Overshooting tops exhibited infrared brightness temperature values as cold as -79ºC.

Bret was in a favorable environment for continued intensification, as shown by low values of deep-layer wind shear from the CIMSS Tropical Cyclones site (below) — and the storm was moving over relatively warm water (Sea Surface Temperature).
