Thank you @SadiqKhan for posting a warning on @MayorofLondon about the #CodeAmber #HeatAlert. Serious question: Why won’t you do the same for #AirPollution ie your primary feed for #CodeYellow and above, never mind #CodeRed HIGH? cc @metecoban92 @EllaRobertaFdn @HealthyAirUK @HealthyAirLDN @MumsForLungs
As the amber heat health alert continues, I’m urging Londoners to follow UKHSA advice. Stay safe in the heat and look out for those who may be more vulnerable 👇🏽

#CodeAmber | #AmberRain is expected to hit parts of England in the next few/24 hours. This is serious ps we’ll be trialling similar references to #YellowAir #AmberAir instead of ‘MODERATE’ AirPollution (which understates ‘risk’ and can mislead people during serious episodes)

Watch out for heavy pulses of rain continuing across England and Wales this evening 🌧️ Ending on a drier note further north - clear spells in the west but cloudier in the east 🌖 ☁️
