Ethylene glycol can be diluted in a solution of 50 per cent water and 50 per cent coolant (or antifreeze!) to lower the freezing temperature of the fluid in your radiator by 60 genres or more. That's cold. But coolant isn't finished amazing you yet.
A severe thunderstorm warning, on the other hand, is not issued until such a storm has been physically observed or is spotted on radar. A tornado watch is issued when conditions may produce a tornado, and a warning is issued when a tornado has been sighted, or when rotation is seen on radar.
Find out more about Flood Warnings. There are a number of ways you find out whether your area is at risk from flooding. The Environment Agency, the Scottish Environment Protection Agency and Natural Resources Wales update their warnings 24 hours a day via the Floodline number. Warning and an Early Warning of the same colour have the same severity but are forecast to arrive at different times. Thus, the difference between a Red Warning and a Red Early Warning is the lead time of the event. When a warning is in force, full information can be found at Met Office Weather Warnings.
