A. Platelets are the tiny blood cells that help stop bleeding by binding together to form a clump or plug at sites of injury inside blood vessels. A normal platelet count is between 150,000 and 450,000 platelets per microliter (one-millionth of a liter, abbreviated mcL). The average platelet count is 237,000 per mcL in men and 266,000 per mcL in women.
The monsoon season begins on June 15 and ends on September 30, but the storms peak between mid-July and mid-August. On average, about half of Arizona receives about half of its annual rainfall during the monsoon. However, rainfall can vary tremendously between distances of just a few miles.
So, as opposed to an individual storm, the monsoon is a specific season of the year. Here in Arizona, the monsoon is essentially a change in the weather pattern. We have winds that typically blow in from the west and southwest, keeping the state fairly dry. Around this time of year, however, the wind flow shifts.
