Two London hospitals were forced to evacuate dozens of patients after being hit with territorial floods.
More than 100 of patients were evacuated from Whipps Cross Hospital in east London after water flooded its basement causing a power outage.
Newham hospital has also asked patients to use other A&Es for urgent care.
A spokesperson for Barts Health NHS Trust which runs both Newham and Whipps Cross hospitals, said: “Patients are asked to attend alternative hospitals where they can. A major incident has been called across the Trust.”
In Worcester Park, a family was rescued by firefighters in a dinghy when their car became trapped by the rising water.
LFB said: “Firefighters rescued three adults and two children who were trapped after their car became stuck in one metre of water in Worcester Park and used specialist water rescue equipment to assist partners at major flooding on Charlie Brown’s roundabout in South Woodford.
“Crews are continuing to support partners at Whipps Cross Hospital today, assisting with removing flood water and ensuring the safety of patients.”
All scheduled surgeries and outpatient appointments at Whipps Cross have been cancelled and ambulances diverted.
A yellow thunderstorm warning remains in place for parts of south-east England.
Last week, more than 180 people died in Western Europe due to the floods.
While about 157 German people died aftermath the flood, only 31 from Belgium died. And about 163 people are still missing.
Other countries like France, Netherlands, Austria and Switzerland have also been affected by the worst flood Europe has been in living memory.
