Sahara Dust Clouds Are Heading to Florida and Beyond
Clouds of dust blown off the Saharan Desert into the southeastern U.S. could affect local weather and make sunrises and sunsets particularly vivid By Meghan Bartels edited by Clouds of dust drifting from the Sahara Desert over the Atlantic Ocean could make for unusual-looking sunrises and sunsets, as well as potentially drier weather, over Florida and parts of the southeastern U.S. in the coming days. What's Happening Between late spring and early fall, dust from the Saharan gets blown out over the Atlantic Ocean every three to five days. When conditions are right, air masses that are filled with this dust can make it across the thousands of miles required to reach North America. Meteorologists call this type of air mass the Saharan Air Layer, or SAL.

Currently, on Friday, a thin SAL is dispersing over Florida, says Ana Torres-Vazquez, a meteorologist at the National Weather Service's Miami office, who adds that this could interfere with some storms carried into the peninsula by a cold front on Saturday. Another layer of dust—this one thicker and denser—may then blow in next week, although that forecast is currently less certain, Torres-Vazquez notes. It's worth noting that the Atlantic hurricane season officially begins on June 1. In general, the SAL tends to dry the atmosphere it drifts through—so some scientists think these dust clouds may actually impede hurricane development. For now, however, forecasters aren't expecting any tropical storms to develop in the Atlantic within the coming week. Sunrise, Sunset The effect that will be most noticeable to local residents as the dust lingers might be unusual sunrises and sunsets. 'When you have Saharan dust or any other kind of particulate, if the sun is coming in at an angle, like during sunrise or sunset,' Torres-Vazquez says, 'it can hit those particulates that are close to the ground just right and result in those different, kind of orangey-reddish colors.' Other parts of the country might also see enhanced sunrises and sunsets during the coming days from a different kind of particulate—wildfire smoke. Canada is experiencing yet another brutal year for wildfires, with nearly 700,000 hectares, or more than 2,500 square miles, burned to date. Right now fires are particularly bad in the provinces of Saskatchewan and Manitoba, in part because of high temperatures stuck over central Canada. Smoke from these blazes is expected to reach U.S. states, including Minnesota, Wisconsin, Illinois and Michigan, in the coming days. Depending on how close the dust and smoke get to Earth's surface, these kinds of particulate matter can be harmful to people's health, particularly for people who are very young or very old and those who have asthma or heart or lung disease.

7.6 magnitude quake hit Caribbean, spurring tsunami alert. Is South Florida affected?
A 7.6-magnitude earthquake slammed the Caribbean Sea — prompting several tsunami warnings, which were later canceled, weather officials say. The earthquake began Saturday night about 130 miles south-southwest of George Town, the capital of the Cayman Islands, according to the U.S. Geological Survey. A tsunami threat was initially forecast for 20 countries and islands, including the Bahamas, Belize, the Cayman Islands, Cuba, Haiti, Jamaica and Turks and Caicos. The U.S. National Tsunami Warning Center had issued an advisory for Puerto Rico and the U.S. Virgin Islands, though it was later retracted. The Caribbean has seen aftershocks, smaller earthquakes, since the 7.6-magnitude quake, said Ana Torres-Vazquez, a meteorologist at NWS Miami. The aftershocks haven't caused any reported damage. The sea has also had no tsunami activity, and South Florida was not impacted, Torres-Vazquez added.
