When rain falls onto the earth, it just doesn't sit there, it starts moving according to the laws of gravity. A portion of the precipitation seeps into the ground to replenish Earth's groundwater. Most of it flows downhill as runoff. Runoff is extremely important in that not only does it keep rivers and lakes full of water, but it also changes the landscape by the action of erosion. Flowing water has tremendous power—it can move boulders and carve out canyons; check out the Grand Canyon! Runoff of course occurs during storms, and much more water flows in rivers (and as runoff) during storms. For example, in 2001 during a major storm at Peachtree Creek in Atlanta, Georgia, the amount of water that flowed in the river in one day was 7 percent of all the streamflow for the year. Some definitions of runoff:1. That part of the precipitation, snow melt, or irrigation water that appears in uncontrolled (not regulated by a dam upstream) surface streams, rivers, drains or sewers. Runoff may be classified according to speed of appearance after rainfall or melting snow as direct runoff or base runoff, and according to source as surface runoff, storm interflow, or groundwater runoff.2.

A fatal grass fire started at the military base Saturday afternoon during a live training exercise. It has now been confirmed to have taken the lives of four Canadian soldiers. 39 more are in hospitals across Alberta, with 19 in critical condition. A CAF spokesperson said the fire was burning for several hours in a training area, but a sudden change in wind intensity and direction spread it towards training soldiers with deadly speed. “Uncommonly strong winds caused the fire to spread rapidly and shift direction towards the range administrative area,” Maj.-Gen. Wade Rutland said Sunday. “The fire was a kilometre away when the wind shifted. It is not normal for a fire to move a kilometre in 30 to 60 seconds.”Rutland is the commander of the 1st Canadian Division and the “higher headquarters” of the unit training at CFB Wainwright. CFB Wainwright is about 200 km southeast of Edmonton.

We have the maps you need to track all the systems ongoing in the Pacific and Atlantic below. Tracking the AtlanticTropical development areasSea surface temperatures Wind shear These are areas of strong wind shear, the difference in wind speed and direction with height, which are shown in purple. High wind shear is hostile to mature tropical cyclones and those trying to develop.(MORE: What is wind shear?)Get More of Our News on GoogleSet The Weather Company as a 'Preferred Source' to get quicker access to the news you value. Dry, dusty airAnother nemesis of tropical systems is dry air. In hurricane season, plumes of dust-laden air stream across the basin from Africa's Sahara Desert, as you can see in the map below. This sinking, dry air squelches thunderstorm development, the building blocks of tropical storms and hurricanes. So areas in the brown shading below are generally unfavorable for development. Atlantic tracks so far this seasonThese are the tracks of systems that were at least tropical or subtropical storms so far in the Atlantic Basin.
