8/26 – Rob’s “Elevating Rain Potential” Thursday morning Forecast

Easterly flow will continue to be a primary ingredient for increased rainfall across the area today. A strong tropical wave will move right across the area today and tomorrow bringing pretty adequate moisture to the area to assist in the increased rainfall potential. The main threat today will be some gusty winds and heavy rainfall (1-3 inches per hour) capable of producing flooding in localized areas where storms form. Friday into Saturday, expecting even more efficient rainfall to penetrate the area increasing localized flooding (2-4 inches per hour) potential for flood prone/low –lying areas. The bright side to this surge of rainfall over the area is that daytime temperatures will stay out of heat advisory criteria as thunderstorms and cloud cover will keep high temperatures in upper 80s to low 90s during the day and low 70s at night.

Into the weekend and early next week, the main threat is the tropical system in the Caribbean. A few models bring it into SE LA on Sunday, whist others brings it into SE LA on Monday. At this point in time, the only thing that can be said with any certainty is that increased winds, rain, and higher sea state will be a factor. Impacts beyond this will depend on what this system wants to do.
