First, what is a hurricane?A hurricane is a rotating low-pressure weather system.The system is born as an area of disturbed weather usually in the Atlantic Ocean. If the conditions are right, the system organizes thunderstorms to create a sort of heat pump to draw fuel from the warm ocean waters. Tropical systems gain strength by drawing heat from the air and sending it upward to be released through condensation of water vapor in thunderstorms.
As these storms move across the ocean or in and around the Gulf of Mexico, they can grow stronger.
When a system has sustained winds of 39 mph, it is classified as a tropical depression. When the winds reach 39 mph or higher, the depression becomes a tropical storm and is given a name.
At 74 mph, the system is a hurricane.

What is the Saffir-Simpson scale and what does it have to do with hurricanes?The Saffir-Simpson Hurricane Wind Scale categorizes hurricanes by wind strength.The tropical system is assigned a category depending on its wind speed. Here are the categories, the wind speeds and what those winds will likely do once the system makes landfall.
Category 1 – 74 to 95 mph: Very dangerous winds will produce some damage: Well-constructed frame homes could have damage to the roof, shingles, vinyl siding, and gutters. Large branches of trees will snap and shallowly rooted trees may be toppled. Extensive damage to power lines and poles likely will result in power outages that could last a few to several days.
Category 2 – 96 to 110 mph: Extremely dangerous winds will cause extensive damage: Well-constructed frame homes could sustain major roof and siding damage. Many shallowly rooted trees will be snapped or uprooted and block numerous roads. Near-total power loss is expected with outages that could last from several days to weeks.
Category 3 – 111-129 mph: Devastating damage will occur: Well-built framed homes may incur major damage or removal of roof decking and gable ends. Many trees will be snapped or uprooted, blocking numerous roads. Electricity and water will be unavailable for several days to weeks after the storm passes. (Category 3 storms and above are considered major hurricanes).
Category 4 – 130-156 mph: Catastrophic damage will occur: Well-built framed homes can sustain severe damage with loss of most of the roof structure and/or some exterior walls. Most trees will be snapped or uprooted and power poles downed. Fallen trees and power poles will isolate residential areas. Power outages will last weeks to possibly months. Most of the area will be uninhabitable for weeks or months.
Category 5 – 157 or higher: Catastrophic damage will occur: A high percentage of framed homes will be destroyed, with total roof failure and wall collapse. Fallen trees and power poles will isolate residential areas. Power outages will last for weeks to possibly months. Most of the area will be uninhabitable for weeks or months.

XENIA — UPDATE @ 2:15 p.m.: The Rumpke trash truck has been pulled from the building it crashed into this morning.
The office the Rumpke trash truck hit was the home administrator's office, Greene County Administrator Brandon Huddleson said. The nursing home administrator was in the front of the building and was not injured.
"We've had some of these issues before [a car hit the treasurer's office on Main Street some time ago]... I wasn't expecting to see a trash truck actually inside our building," he said.
Huddleson said, "by the grace of God, the folks that were in those offices were out in the field or out in other places in the building."
He noted it's hard to imagine that anyone who would have been in the building could have escaped.
There are about 50 residents in the building, but the entire wing where the truck hit is all administrative/maintenance offices.
There was some ancillary flooding in the damaged portion of the building, because of the sprinkler system that activated. Otherwise, he said, it's business as usual at the nursing home.
UPDATE @ 12:45 p.m.:
A building support will have to be installed at the Greenwood Manor nursing home before the Rumpke trash truck lodged inside a wing of offices can be pulled out, Greene County building inspectors said.
No employees were in the wing when the truck crashed into the home, 711 Dayton Xenia Road, about 8:45 a.m.
A Rumpke official said the company and police are continuing to investigate the incident.
The trash truck driver was taken to Greene Memorial Hospital, where he was to be treated for non-life threatening injuries, Xenia police said.
A trash truck has crashed into a nursing home on Dayton Xenia Road in Xenia Thursday morning.
Fire crews were initially dispatched to the Greenwood Manor, 711 Dayton Xenia Road, around 8:45 a.m. on reports of a fire alarm from the building.
While crews were still responding, dispatchers said a trash truck had crashed into the building.
Initial reports indicate one person was injured in the crash and the wing where the crash occurred has been evacuated.
Additional details were not available.

XENIA — UPDATE @ 6:22 p.m.: The driver of a semitrailer that crashed on the U.S. 35 West Bypass in Xenia will be cited for speeding and failure to control after his explanation to authorities -- that a deer ran out in front of his rig -- was knocked down by witnesses, said Sgt. Matt Cleaveland, Xenia Post, Ohio State Highway Patrol.
The driver, who was not identified by name, was not injured and managed to climb out of the wreckage on his own, the sergeant said, but admitted that he was driving at 68 mph in heavy rain in a zone where the posted speed limit is 45 mph.
Cleaveland said the driver lost control of the rig, which went off the left side of the road and then the right before crashing through guardrail and coming to rest on its side down a 30-foot embankment.
A heavy downpour was occurring at the time of the accident, which was reported just after 1 p.m., the sergeant said.
A section of guardrail had to be cut away and the trailer, which was carrying an estimated 5,000 pounds of brake drums, had to be taken apart as well.
Traffic on the bypass was rerouted to U.S. 68 and into Xenia, then back onto U.S. 35 West.
The bypass is expected to be cleared fully by 7 p.m., the sergeant said.
