It ’s difficult to be mad about hot atmospheric condition   without feeling like   a minor character inDon’t appear Upwho is n’t need the big looming asteroid seriously . It ’s even more unmanageable when a heatwave is to be observe by something as apocalyptical - sounding as " rake rain " .

Well , good news program UK , because you ’re about to be make by both . After a heatwave that will see temperatures rise to the high ascertain this yr , profligate rain could impinge on the country on Friday .

profligate rain is red - discolour , because of relatively high concentrations of red dust or particles mixed in with the piddle . According to theMet Office ,   " bloodline rainwater " is a colloquial term and " is not really a meteorological or scientific term . "

It is not go through often in the UK , but every now and then dust can be carried to the island . In this case , the blood rainfall ( should rain coincide with the storm passing over the UK ) will be make by a plume of dust from the Sahara , after make up its path across the   Mediterranean . It is gestate to arrive on Friday sunrise .

" Aerosol prognosis from the Copernicus Atmosphere Monitoring Service ( CAMS ) observed another large plume of Saharan dust moving west across the Atlantic between 12 - 17 May and heading towards the Caribbean , "   CAMSsaid in a statement .

" accord to the prognosis , the plumage will also strain western Europe on 20 and 21 May . CAMS data supervise the dust transportation every twelvemonth and throughout all level , while also noting that this year has shown , and continues to show , high levels of dust transport across the Mediterranean and parts of Europe . "

If it does n’t rain down , the UK – and the Carribean , should the storm also make it across the Atlantic – may still see unusually red sky .

" Most of the dust transport is probable to be at higher altitudes which could lead to hazy skies rather than impacts on surface strain quality , " Senior Scientist for the European Space Agency ’s Copernicus Atmosphere Monitoring Service   Mark Parrington tell Mail Online . " It may also be mixed with some rain , which is also forecast for Friday , so there could be open sedimentation on cars after the rain has cleared . "
