Persistent rain and drizzle in Fort Worth, Texas has meant that this week's NASCAR Sprint Cup Series race at Texas Motor Speedway will now take place on Monday afternoon, after Sunday proved to be a washout.
The chilly morning saw persistent heavy rain, but there had been hopes that the race could go ahead later in the day with forecasts promising less precipitation in the afternoon. However, the skies continued to deliver light showers, drizzle and heavy mist that thwarted track drying efforts.
With daylight fading there was still optimism that the track could go ahead as an evening race under the floodlights at the 1.5-mile oval, but just when it appeared that the track was nearing a race-worthy condition and the radar was showing an opening in the cloud cover heading toward the circuit, another sharp downfall promptly undid all the drying efforts.
Even though NASCAR had five of its revolutionary new Air Titan units at the track augmented with older units and traditional jet drying units, a problem with 'weepers' - where rain that has previously permeated the track surface then persists in oozing back up through seams in the asphalt - proved a particularly intractable problem on Sunday.
Finally race officials were forced to bow to nature, and at 6pm local time the announcement was made that the Duck Commander 500 would not be held on Sunday after all, and would instead be held over to a planned start at 11am local time (5pm BST) on Monday. It's the first time this season that a Cup race day has been completely rained out, although the weather has already impacted several race weekends in 2014 albeit to a lesser extent.
The US National Weather Service predicts warmer temperatures in the mid-60s for Monday and a dry morning, but there is still up to a 40 percent chance of rain from midday onwards which could yet cause problems getting the race underway. The chance of rain drops to 20 percent by nightfall, meaning that a floodlit evening race remains a possibility.
Tony Stewart previously won pole position for the 334-lap race, the seventh of the Cup season.
