Torrential rains and high winds prompted the cancellation of more than 640 Canary Islands flights over the previous 36 hours, Spain's AENA airports operator said on Monday.
Most of the cancellations took place on Sunday, when 540 flights to and from the Atlantic archipelago had to be axed and another 54 rerouted as tropical storm Hermine battered the islands.
By 8:40 am (1040 GMT) on Monday, another 102 flights to and from the islands had been cancelled while six others were re-routed to other destinations, AENA said in an update on Twitter.
Most of the cancellations affected the two airports on Tenerife, the largest of the Spanish islands, which are located off the northwestern coast of Morocco.
AEMET said the rain would continue on Monday but would be "less intense" than at the weekend, saying the downpour had resulted in the islands' "wettest September on record".
