Tropical Storm Hilary Update - August 20th, 2023
National Oceanic and Atmospheric Administration forecast for tropical storm Hilary.
National Oceanic and Atmospheric Administration (NOAA): We'll be monitoring the area along the ID/OR border as deep moist convergence between Boise and Pendleton is prevalent across all guidance with a general QPF maximum co-located on the eastern flank of the remnant circulation of Hilary once it reaches area latitude.
Have added an MRGL across south Texas as guidance indicates a slightly earlier arrival of the lead wave moving across the Gulf. A deep moist axis extending from the western Gulf into the S TX coastal plain indicates a period of heavier rainfall potential at the back end of the D2 ERO with most guidance indicating 1-1.5" QPF max within a 6 hr time frame between 06-12z Tue.
