Event narrative

Report of flooding at the park office along Bristoria Road.

Wider weather episode

Overnight sub-severe convection and remnant boundaries from said convection acted as initiating mechanisms for development later in the morning and afternoon hours. A moist and unstable environment with up to 2500 J/kg MLCAPE and 30 knots of effective shear supported storm organization and maintenance. Favorable DCAPE between 800-1000 J/kg resulted in some instances of damaging wind. In addition, slow cloud bearing layer wind and PWAT values up to 2.0 was sufficient for instances of flash flooding.
