Glendora Random Weather Fact
Most of the severe weather is seen in the LA Metro area, is caused by micro bursts--not tornadoes. A "micro burst" is a small area of rapidly descending air beneath a thunderstorm. When the descending air hits the ground, it quickly spreads out in all directions, causing very strong, straight-line winds. These winds are commonly as strong as 40-60 mph but can exceed 100 mph at times. Micro bursts occur over a rather small space-scale, typically the area affected is less than 2.5 miles in diameter.
