From early July until mid August, our summer has been uncommonly hot and dry. While we did receive one or two well-timed rains, the threat of forest fires has been unnerving.<\/p>\n
I doubt the forest fire risk profile has officially changed at this moment, but we received heavy rain today. Looking at a weather map, I think I can see why.<\/p>\n
The map shows us under a low pressure system, with a cold front also present. Although I’m not trained in weather, my simple explanation for the heavy rain is this: The low pressure system, which comprises warm, moisture-filled air (some of tropical origin) is colliding with the cold front. As the air in the low pressure system cools down, it can no longer hold so much moisture, so drops it as rain. The heavy rainfall results from the plunge in temperature as the low pressure system hits the cold front.<\/p>\n
Over the next three days more rain is forecast:)<\/p>\n
