Preheat oven to 350 degrees. Place potatoes and garlic on a rimmed baking sheet. Drizzle with olive oil and season with salt and pepper. Toss to coat. Roast until dark golden brown, 30 to 45 minutes. During the last 5 minutes of roasting, increase the temperature to 500 degrees and sprinkle with rosemary.
A downburst is a strong downdraft that results in an outward burst of damaging winds on or near the ground. Downburst winds may begin as a microburst and spread out over a wider area. [+] A microburst is a small concentrated downburst that produces an outward burst of damaging winds at the surface. Microbursts are generally small (less than 4km across) and short-lived, lasting only 5-10 minutes, with maximum windspeeds up to 168 mph. There are two kinds of microbursts: wet and dry.
Microbursts are small scale, intense local downdrafts which, on reaching the surface, spread outward in all directions from the downdraft center. This causes the presence of both vertical and horizontal wind shears that can be extremely hazardous to all types and categories of aircraft, especially at low altitudes.
