Monday started well with sunshine, 4.5 hours, but a warm front was approaching and by 14.15 the first rain began to fall producing 5.9mm of rainfall. That eased away during the evening but just after 04.45 Tuesday morning a cold weather front arrived with intense rainfall that produced another 23.7mm of rainfall by 08.00 on Tuesday. The rainfall for the past twenty-four hours totalled 29.6mm making it the wettest day since 24th May 2018 when 31.9mm was recorded, which brings the September total to 48.6mm being 79% of the 35-year average.
The deluge means that the rainfall for September at 48.6mm now exceeds the evaporation total for September, which was 47mm.
All the cloud and rain has been produced from weather fronts associated with ex-hurricane Humberto, now in the Eastern Atlantic.
The maximum temperature on Monday was exactly average at 18.6C, which occurred at 12.52, before the cloud increased and rain arrived when the temperature dropped 4C. Overnight the thermometer did not drop below 14.6C being 5.3C above average as the wind continued from the south for much of the past twenty-four hours.
The barometric pressure has been falling for the past four days, with a minor ridge yesterday, falling 28mb from a maximum of 1035.7mb to 998.7mb today as ex-hurricane Humberto approached.
Update on Tuesday at 16.15: another 10.3mm of rain since 08.00 with more tonight.
