What Is A Haboob?

Tools

By By Steve Pool

SEATTLE - A Haboob is a very strong dust storm that moves through hot and dry regions, including the Desert Southwest. With wind speeds up to 50 mph, they form from strong downdrafts in nearby thunderstorms. The winds pick up dust and sand and can make a wall of blowing sand as high as 3,000 feet.

Along somewhat similar lines are "sirocco" winds, which is a hot wind that blows north-to-northeast across the Sahara Desert.

As it blows across the Mediterranean Sea, it picks up moisture, and then plows into southern Europe as a hot and humid flow. It can bring triple-digit heat with uncomfortable humidity to areas such as Italy and southern France. It can also bring a lot of dust.

Not to be outdone are "williwaw" winds, which are violent winds that come off mountainous coastal terrains and can destroy sailing ships along the coastline.

When I saw this dramatic cloud to the north, it reminded me of smoke, rising in billows until it hits the jet stream, then it's pulled hundreds of miles east. I had to capture it quickly. Within minutes the effect had faded.

For my girlfriends birthday we had a party at her parents. We knew the nest was there but the owner hadn't seen or heard the osprey for a day or two. He asked me to fly my drone up and see if any was wrong. I flew up and found that there were two eggs inside.

The growing season has been great.

The secret to this garden is simple.
I used recycled grass clippings.
