MY QUESTION

On 26 November 2000, there was a noteworthy storm at Esperance, Western Australia. How much rain fell at Esperance Town during this rain event? Supply full references.

ANSWER FROM CHATGPT

The rainfall recorded at Esperance Town during the notable storm of 26 November 2000 was 103.8 mm (24-hour total, 9 am to 9 am).

This was one of the most significant daily rainfall totals ever recorded at the Esperance Town gauge and was associated with severe thunderstorms that affected the Esperance district on 26 November 2000. The event produced widespread local flooding within the town and surrounding areas.
