Fire Marshal says use care with fireworks in dry conditions

While some parts of the state have been without rain for more than a week, there are currently no burn bans are in place in Iowa. Dubuque County will be under a burn ban starting Thursday morning. The head of the state fire marshal’s arson and explosives bureau says it’s important with the dry conditions to be especially careful celebrating the Fourth of July. Ron Humphrey says things could be worse. “It’s not quite as bad as it is in the spring or fall, when everything is all dried out, at least the grass and the crops are still green but keep in mind a small fire could spread quickly with the right conditions, and the right material,” Humphrey says.

“Use good safety precaution when using the fireworks we want to make sure that with the dry conditions that when you use sparklers or shooting off fireworks by permit the area is safe for both people and the surrounding environment,” according to Humphrey. The Dubuque County burn ban goes into effect at eight a-m Thursday. More counties could be added in the next few days without significant rain to improve the dry conditions.

IA DOT warns of possible pavement blow-ups

News, Weather

July 3rd, 2012 by Ric Hanson

Motorists traveling in Iowa should be aware that the mercury might not be the only thing to rise during the sweltering summer heat. Pavement blowups occur when thermal expansion forces the pavement to buckle and shatter. A number of such incidents have been occurring this week.

Example of Pavement blow-up incident

In a typical year, Iowa DOT maintenance equipment operators spend 2,000 to 4,000 hours making temporary repairs of pavement blowups and another 6,000 hours replacing these pavement sections, costing an average of $400,000 annually. Many of the blowups only result in a small pothole or small chunks of concrete lying around the pavement joints, but they must still be repaired.

Unlike scheduled maintenance, pavement blowups occur spontaneously and motorists receive no advance warning. Once a blowup is reported, it takes time to erect a work zone and notify the public. The Iowa DOT urges motorists to pay special attention to pavement surfaces when driving during afternoons with 90-degree or hotter temperatures. Use caution and reduce your speed when approaching broken pavement areas.

Motorists who witness a pavement blowup are asked to contact the nearest law enforcement agency to ensure traffic is routed around the blowup until work zone signage and repair crews are on the scene.

Heat advisory for most of Iowa, heat warning for northern Iowa

News, Weather

July 3rd, 2012 by Ric Hanson

The National Weather Service has issued a four-day-long “excessive heat advisory” for most of the state and parts of northern Iowa are under an “excessive heat warning.” The Advisory runs through 7-a.m. Saturday, for all but the far west and southwest counties, where a separate Heat Advisory is in effect from Noon today through 8-p.m.  That includes Monona, Harrison, Shelby, Pottawattamie, Mills, Montgomery, Fremont and Page Counties. Heat indecies are expected to climb to around 105 degrees or higher this afternoon in those counties, and from 100-to 105 for the rest of the area. 

Meterologist Kevin Skow works in the National Weather Service office in Johnston. He says “This is an unusual situation where we’ve had a very persistent high pressure system over us that’s pumping up a lot of heat from the south.”  This prolonged period of super-high temperature readings during the day is happening because things cannot cool down overnight and Skow says it’s due to a “very moist” air mass hovering over the state. “It takes more energy for water vapor to cool off and since it’s so moist, the air just simply can’t cool off overnight as much as it could, say, in the springtime when we usually have drier air over us,” Skow says. Smoke from the Colorado wildfires has drifted over Iowa, but experts say it won’t cause health problems.

“The smoke is really high in the atmosphere,” he says. “It’s up at 20,000-30,000 feet and the only effects that Iowans will really see from it (are) generally some hazier skies and some redder sunrises and sunsets.” By eight o’clock this morning (Tuesday), heat index readings across the state indicated it already felt like it was 80 degrees in most locations. On Monday Nebraska’s governor declared a state of emergency in his state due to drought conditions there.
