On This Date: An F5 Tornado Roared Through An Iowa College
On June 17, 1882, 143 years ago today, an F5 tornado tore an estimated 105-mile long path through parts of six central Iowa counties, claiming 68 lives and injuring another 300.
According to the National Weather Service and tornado historian Thomas Grazulis, the twister killed 10 near the towns of Rippey, Kelley and southwest Marshal. County before it barreled into the town of Grinnell. At least 39 were killed and 73 homes destroyed in Grinnell, about 45 miles east-northeast of Des Moines.
Both buildings of what was then known as Iowa College were destroyed, and three students were killed in their dorm rooms that day.
Another 13 fatalities occurred southeast of Grinnell near Malcolm and Brooklyn, Iowa.
Of the Hawkeye State's 11 known F5 or EF5 tornadoes, this was the earliest on record. It happened without warnings, as the first public tornado warning wasn't issued until 1952. It also happened over 100 years before the nation's Doppler radar network was built.
This destructive tornado didn't spell the end for the college, though. Once news of the school's financial challenges after the tornado filtered through the press, and after one of the town's founders visited the Chicago Board of Trade, donations from across the nation allowed the school - now called Grinnell College - to rebuild.

Air-quality alert for Broward issued due to Everglades fires. Smoke moving east
The National Weather Service issued an air-quality alert for all of Broward County starting Thursday evening and continuing through Friday morning due to two large wildfires burning in the Everglades. The alert, issued around noon Wednesday, will go into effect at 10 p.m. and run through 9 a.m. Friday, the Miami weather service said, as smoke is expected to drift eastward from the Everglades blazes. The Mile Marker 39 Fire is now covering 1,600 acres, and the Sawgrass Fire is at 250 acres, the National Weather Service Miami reported Wednesday. Both fires were 0% contained as of Wednesday morning, according to the Florida Forest Service. READ MORE: Wildfires in Everglades spreads to more than 1,800 acres, smoke affecting Broward Many Broward residents have called 911 to report the smell of smoke as far as the eastern part of the county, according to Fort Lauderdale Fire Rescue. Here are steps to take to limit your risk of smoke inhalation: The National Weather Service recommends that vulnerable populations, including people with respiratory conditions, limit their time outdoors. Officials are urging the public to track local air quality through the Environmental Protection Agency's AirNow website, which provides updated data in real time. As of Wednesday morning, the air quality in much of Broward was listed as moderate, according to AirNow. During the early morning hours, the air quality in the county was considered unhealthy. Officials are also warning commuters to be extra cautious while driving as smoke could impair their visibility of the roadways. Drivers should use their car's air conditioning on recirculate.

Hurricane Erin to Menace US East Coast Beaches Into the Weekend
Hurricane Erin is triggering dangerous beach conditions across much of the US East Coast that will likely last into the weekend, as the storm pushes north in the waning days of the summer travel season. The risk of powerful currents that can sweep strong swimmers out to sea is forecast to reach high levels by Friday at popular vacation destinations, including Cape Cod, Martha's Vineyard and Nantucket in Massachusetts, the Hamptons on Long Island and Delaware's Rehoboth Beach. Heavy winds and waves up to 20 feet (6 meters) tall are possible in the worst-hit areas before beginning to ease Saturday.

Beach Warnings Issued as Hurricane Erin Nears the East Coast
Hurricane Erin is expected to turn away from the United States but is likely to bring a dangerous threat in the coming days: rip currents along the East Coast of the United States and Canada, as well as Bermuda and the Bahamas. The life-threatening risks of rip currents were highlighted last month, when Malcolm-Jamal Warner, the actor who rose to fame as a teenager playing Theo Huxtable on 'The Cosby Show' in the mid-1980s, drowned while swimming at a beach on the Caribbean coast of Costa Rica. He was swept away by a rip current, channels of water that flow away from the shore and can drag people along. The National Weather Service has warned that Erin could produce 'life-threatening surf and rip currents, and local authorities have issued warnings for swimmers this week in areas affected by Erin. Rip currents, even from distant storms, are the third-highest cause of death related to hurricanes. At least three dozen people in the United States have drowned in the surf so far this summer, most of them caught in rip currents, according to the National Weather Service, which tracks surf-zone deaths across the country. One swimmer died and four others were rescued from the waters off Seaside Heights, N.J., after they became caught in a rip current on Aug. 11, when lifeguards were off-duty, the authorities said. Earlier in July, Chase Childers, a former minor league baseball player, died after rushing into the surf in Pawleys Island, S.C., to save swimmers in a rip current, the police said. Fatalities do not just occur in oceans. In the Great Lakes region, rip currents caused an average of 50 drownings per year from 2010 to 2017, Chris Houser, the dean of science at the University of Waterloo in Ontario, Canada, said. Can you see a calm strip of water cutting through the waves? Rip currents occur when water flows away from the beach through a narrow channel that has been created by an underwater feature or a sandbar. They are easiest to see from an elevated position like a beach access point, and are harder to spot when a person is closer to the water. From land, a rip current can appear relatively calm on the surface, as a strip of water that extends out from the beach between breaking waves. Its appearance can be deceiving, because the forceful flow of water away from the shore can sweep a swimmer far into the body of water. The current can also appear as a patch of darker water stretching away from the beach, or as a distinct offshore flow. Rip currents are swift and unrelenting. They can move at speeds of up to eight feet per second, which is faster than the pace of an Olympic swimmer. But drownings often happen with far weaker currents, said Gregory Dusek, a senior scientist with the Ocean Service at the National Oceanic and Atmospheric Administration. 'It doesn't have to be moving that fast to cause a problem,' Mr. Dusek said. 'It just needs to be pulling you enough to get you from where you can touch to where you can't.' The currents can occur at any time and in any conditions, but they are most dangerous when waves are two to three feet high, Mr. Dusek added. There is also added risk in late summer, when tropical storm systems and hurricanes can move through a region and prompt strong waves, even on clear, sunny days. 'You can have a storm far away driving pretty large waves, and you can have strong rip currents where you are, even when the weather seems fine,' Mr. Dusek said. Check the surf forecast at your beach. NOAA maintains beach weather forecasts for several popular destinations, which contain information about rip currents and waves, at Surf zone forecasts also assess the low, moderate or high risks of rip currents associated with your destination beach. Some lists of safety tips from government agencies also state the obvious for people dipping into the surf: Make sure you know how to swim. Read signs and avoid swimming near piers. Try to swim at a beach that is under the watch of lifeguards, and ask them about the conditions before you enter the water. Comply with their orders, and read and follow instructions from official posted signs. Do not swim alone or within 100 feet of piers and jetties, because rip currents flourish alongside them, NOAA recommends. Families with children should swim near a lifeguard if there is one. It also helps if children bring something that floats into the water with them, such as a boogie board, a surfboard or a lifejacket, all of which can help weaker swimmers navigate a rip current. Hopefully, you will never need the advice in the next section. Don't fight the rip current. Many people panic when they get pulled into a rip current, which leads them to waste energy and make irrational decisions, Mr. Dusek said. If you find yourself carried off by a rip current, try to relax and evaluate your surroundings. Remember that a rip current will not pull you under, he said. And don't try to swim against it. Not every rip current is the same, and you may use different strategies depending on the water's movement and your swimming abilities, Mr. Dusek said. It is possible that the current itself will circulate back to shore. If so, float. The rip current is generally narrow, so try to escape it through its side, rather than head-on. Strong swimmers should move in a direction that follows along the shoreline, or swim toward breaking waves and then at an angle toward the beach, he said. 'If you don't think you can do that, or you feel like you're swimming anywhere in particular, you want to just float and wave your hands and call for help,' Mr. Dusek said. It's important to stay above the water and avoid exhausting yourself to give time for a lifeguard to reach you or for someone on the shore to call 911. To do so, you can also embrace the 'flip, float, follow' strategy, which involves flipping on your back to float above water and following the current until it takes you past breaking waves or back to shore. How to help someone stuck in a current. Rip current drownings often occur when bystanders wade into dangerous conditions to help another person. To assist someone safely, you can help direct them to swim parallel to the shore or flip on their back to float. If you are near someone stuck in a rip current, alert a lifeguard. If there is no lifeguard on duty, call 911. Even if the person escapes the rip current, they may still need lifesaving support, Mr. Dusek said. For swimmers who are pulled by the current closer to the shore, give them something that floats to hold onto, such as a boogie board or a cooler. If you feel like the only option is to enter the water — and you're a strong swimmer — it's important to still bring a flotation device, Mr. Dusek said. Jenny Gross contributed reporting.
