Nicole as a subtropical storm. (CIRA/NOAA)A subtropical storm is different from a tropical storm, hurricane and even a nor'easter - and it can mean a lot of rain, wind and rough sea conditions for those living along the coast. Subtropical storms in the Atlantic Basin can occur one or more times each hurricane season, and are a mix of two different, familiar storm types. We will break down these two more common storms and explain how subtropical storms fall between them. Type 1: Tropical LowsAlso called tropical cyclones, these are low-pressure systems fueled solely by heat energy released when water vapor that has evaporated off warm ocean water condenses into liquid. Due to all this heat, the core circulation of a tropical cyclone is warm, and its strongest winds are usually found near its center. With low wind shear and moist air, tropical storms can intensify into hurricanes. Most storms that impact a wide part of the Lower 48 are extratropical lows. Think of winter storms, lows that slam into the West Coast or storms off the coast of the East Coast.

TOLEDO, Ohio (AP) — Some Ohio residents have been ordered to evacuate because of the release of a chemical that can cause burning of the eyes, nose, mouth and skin, and other residents have been told to shelter in place, the city fire department said Wednesday. People within a 1-mile radius of the “hazardous materials release” were ordered to evacuate at about 10:50 p.m. Tuesday. The shelter-in-place order was issued for Toledo residents within a 3-mile radius beyond that area. Dense fog and haze hindered visibility in the city of about 265,000 people and local news stations reported smelling a plastic-like odor. The dense fog lingered this morning. The National Weather Service has issued a a dense fog advisory until 10 a.m. Once the fog clears out, it will make way for sunny skies through the rest of the day, but winds will remain light and variable. Winds will mostly be coming from the northeast, but low wind speeds will not help much in clearing out the chemicals in the air any time soon, The Weather Channel meteorologist Miriam Guthrie said.

And while some of you will have clear skies, rain and clouds could impact the view for others. Here's what you need to know about the Orionids and your forecast:Fast factsPeak day: The meteor shower peaks Wednesday night, Oct. 21, into the early hours of Thursday morning, Oct. 22. Peak time: From midnight to dawn are the best hours to catch the meteors streaking through the sky, so plan on a late night or really early morning. What the Orionids are known for: The Orionid meteors are known for their brightness and their speed. As they streak across the sky at around 41 miles per second, the meteors leave behind a glowing "train" that can last several seconds to minutes. While you can make the perfect plan to catch the Orionids, the key to stellar viewing is still in Mother Nature's hands. The good news is that many of you should have good meteor shower-watching conditions. Much of the central and eastern U. S.
