Hail storm


 We wouldn’t normally expect to get any serious rain here until late October or even into November. 

Mid-storm: hail, rain and run-off


Hail stones:  the wall is 24 cm wide
and the vertical post 15cm  in diameter














However, on 3rd October we had an unusually early storm:  dark clouds gathered, thunder rolled ever nearer, and then came a noise like an approaching train as the wind came closer and hit with a vengeance.  We had torrential rain for about 30 minutes plus hail on a grand scale!  Hail is common on the highveld but is far less frequent here in the lowveld.  The noise of the hail-stones hitting the roofs and the windows was incredible.  We measured the stones afterwards and the biggest were over 5 cm in diameter so we were lucky to have only one window broken.  Trees and shrubs in leaf were shredded and there was debris everywhere:  four days later, we are still clearing it up.  As usual with heavy rain, there has been much erosion of paths and tracks. 

The river in our valley flowing more strongly than ever
While we were clearing up immediately after the storm we became aware of a rushing sound from the valley below the lodge:  our dry river was in spate, flowing fuller and faster than we have seen in our three years here.  It was the first time that this river has flowed since April-May 2010.  Many of the dams in the reserve that have been relatively empty have benefitted greatly from the run-off.

With further rain later in the day (mercifully gentle!) we had a total of 32 mm, and another couple since.  By next morning the lawns in the lodge had greened up beautifully.  The grass out in the bush is turning green too and no doubt the trees will produce leaves (again, in the case of those that lost them to the hail.)  Given the early nature of this rain, we hope that there will be more before too long and that all the new growth will not burn up in the heat if we have to wait many weeks.
