ALT Current fire risk outlook for Tuesday for Southern California from NOAA SPC. It now depicts two separate/discontinuous "extremely critical risk" zones, one in central San Diego County and the over in western LA/eastern Ventura County.
ALT Snapshot of time series plot showing 24 hour precipitation accumulations as predicted by each ECMWF ensemble member for a point near LAX. It depicts a high probability of at least light showers next weekend, though some members are still completely dry (and others show some heavier showers), an indication of very high uncertainty at this time.

ALT A schematic showing the typical climate science workflow in extreme event research and opportunities for improvements. The “bare minimum” workflow is suggested from downloading data to publishing results. Annotation is then shown for an extension of this work by additional steps including running an Earth System or Integrated Assessment model with optional processing steps. Along with this workflow, different opportunities for improvement are indicated in another style. This graphic is taken from Figure 3 in Kretschmer et al. (2024) in Atmospheric Science Letters.

ALT Line graph time series of slobal-mean surface temperature for August, from 1850 to 2023 using Berkeley Earth (1850-2022), ERA5 (1940-2023), GISTEMP (1880-2022), HadCRUT5 (1850-2022), JRA-3Q (1948-2022) and NOAAGlobalTemp (1850-2022). There is interannual variability and a record long-term increasing trend.
