A slow moving pre-frontal trough led to gusty showers and thunderstorms with very heavy downpours last night. The Bermuda Weather Service recorded 0.95″ of rain yesterday, much of which fell as showers organized into gusty thunderstorms overhead. These bands of showers produced isolated gale force gusts around the island and dropped much of yesterday’s rain in a 30minute period. Another interesting side effect of the gust front and associated heavy rain was that the temperature dropped from 71.0°F to 65.0°F in 15minutes from 8:00pm to 8:15pm at my PWS. Temperatures then continued to slowly fall in the rain behind the gust front bottoming out around 62-63°F.

The active pre-frontal trough passed to the east of Bermuda late last night and slow moving cold front crossed the island this morning with light isolated showers. It has become nearly stationary to the east. More rain is possible in the coming days and into the weekend as a trough quickly moves through the area from west to east, and again on Monday morning as another cold front blows through from the west.

Unofficial rain reports from Wunderground PWS around the island from yesterday:

  • “Harrington Sound,” Smith’s – 1.78″
  • “Tucker’s Town,” Hamilton – 1.24″
