Guacamole lovers, beware: The crystal ball isn't looking so bright for avocados.

Hot weather at the peak of avocado-growing season last June means this Spring California farmers expect to have the smallest avocado crop in the last 10 to 20 years. Americans buy almost 1 billion pounds of avocados annually, and this number is increasing.

Unfortunately, California farmers, which normally supply 85 to 90 percent of domestic avocados, foresee harvesting approximately a third less fruit than they did in 2008. This increased demand and smaller supply will mean a rise in prices.

While avocados will abound during bowl season, the California Avocado Commission predicts they'll be in short supply by the time Cinco de Mayo rolls around. Experts are guessing that the shortage will come late Spring to early Summer, when imports from other countries, such as Mexico and Chile, are at their lowest levels.

I'm wondering if this anticipated price increase will mean a rise in cost at restaurants and dining establishments as well. Come Cinco de Mayo, will you still make guacamole if it means paying $2 for an avocado?
