If rain falls on 31 October, it will mark the first rainy Halloween in Los Angeles in over ten years, the New York Post reported.

The weather service cautioned that outdoor festivities and candy runs are likely to be impacted by the rainfall. Advances in numerical weather prediction models have improved short term forecast reliability to about 90 per cent accuracy for five day outlooks. [1][3]

Halloween traditions trace back more than 2,000 years to the ancient Celtic festival of Samhain, which marked the end of the harvest season. Weather forecasters note that the exact timing and precise locations of the heaviest rainfall for the upcoming weekend remain uncertain. [1][4]
