SUMMARY as at 02:27 on 19 Dec 2018
- Thames Barrier open
- River level in Central London is about 0.5 metres lower than predicted
- River flow at Kingston within normal range
- No local Thames flood alerts
PLA EBB TIDE FLAG WARNING
If the PLA flow status differs from the reported Kingston flow above, this is usually because the latter is more recent.
RAW DATA as at 02:27 on 19 Dec 2018
For those of you who prefer to see the actual numbers on which the summary above was based, here is the raw data. Please note the explanations and legal note below the data.
|Kingston flow gauge||flow rate 53 cumecs (m3/sec) and increasing|
as at 01:30, 19 Dec - latest available data
Tide gauge data is obtained in real time from the Port of London Authority (PLA), based normally on measurements in the previous 5 minutes. "Observed" is the actual gauged height in metres above local chart datum. "Predicted" is the astronomical prediction from the tide tables. "Surge" is the difference between the two, which typically is caused by current or recent weather conditions. The Kingston flow gauge reading and flood alert information are extracted in real time from the Environment Agency (EA). The barrier open/closed status is based solely on the difference in recorded river levels either side of the barrier (Charlton & Silvertown) and assumes accurate readings from those gauges.
I am grateful to PLA and EA for permission to use the above data.
Legal note: The recording and capture of the data is performed by automatic processes, and the data is essentially unvalidated at the time of display here. Accuracy is not guaranteed. PLA, EA and I do not accept any responsibility in law for the information presented here. - Richard Jennings
