Officials are waiting for a break in unsettled weather to launch the 20th annual America's Challenge gas balloon race.
The initial launch for the seven teams participating in this year's distance race was Saturday, but showers and thunderstorms over the weekend forced race officials to delay.
Officials say they must consider weather conditions both for the launch at Balloon Fiesta Park in Albuquerque and downrange across the country for the two or three days the balloons are expected to be aloft.
The next briefing is scheduled Monday evening.
If conditions are favorable, balloons could launch overnight or later in the week. The period of time during which the race can commence closes at midnight Wednesday.
This year's competitors include pilots from the U.S., Germany, France, Poland and Spain.
