The Environment Agency Manager for Herefordshire and Worcestershire Dave Throup has warned that more dust from the Sahara desert is expected to blanket parts of the country this evening.
Loads more Saharan dust on its way (map for 6pm today) Tonight's rain likely to deposit much of it on us! http://t.co/ai0LpSSrAf
Higher numbers of complaints about breathing difficulties are thought to have been brought on by record pollution levels in recent days.
Air pollution in the east of England reached the top of the scale as a 'perfect storm' of conditions blanketed parts of the country.
Our region is one of the worst-affected by "very high" levels of air pollution today, with much of the East stuck under a cloud of smog.
