A strong cold front crossed the island with extensive and slow moving shower activity on Monday. The very active front brought between 0.50″ and 0.75″ of rain to the island on Monday – much needed rains as November has been relatively dry so far. Behind the front, today strong north-northeasterly winds are ushering in cooler and less humid weather, with some lingering post-frontal isolated passing showers.
Strong north-northeasterly flow is expected to continue through Wednesday. This flow then veers overnight Wednesday into Thursday, becoming more northeasterly. This is in response to either a wave or an area of low pressure forming along Monday’s cold front which, by Wednesday night, has stalled to the south through east of Bermuda. This wave then pushes westward towards Bermuda, crossing the island on Thursday night. There is potential for heavy rain, thunder, and gales to develop in the northeasterly flow ahead of the wave or area of low pressure. Such an area of adverse weather could impact the island on Thursday.
The official forecast (from the Bermuda Weather Service) for the second half of this week should therefore be monitored closely for updates if or as this system develops.
