Despite talk of an improving economy and a surge in stock markets, doomsayers have warned of tougher times ahead for Americans with an imminent financial crash looming in the near future.

Three analysts, with expertise on finance and trends, told the USA Today Monday that the worst of the financial crisis was yet to hit the nation.

Gerald Celente from the Trends Research Institute talked of an impending economic 9/11 situation, that he believes will result from the shortcomings or lack of control from lawmakers in dealing with economic disasters.

Celente, who is long known for forecasting trends since 1980, predicts that dollar will crash, thereby leading to less purchasing power and unemployment.

2012 is when many of the long-simmering socioeconomic and political trends that we have been forecasting and tracking will climax, Celente said in the report.

When money stops flowing to the man on the street, blood starts flowing in the street, the trend setter added.

The publication also profiled Harry Dent, who authored a book titled The Great Crash Ahead.  Dent foresees a stock market crash around 2013 or 2014 and believes stocks are given an artificial short-term boost.

He had initially predicted a crash in 2012. However, as the central banks are pumping so much money into the market now, Dent has pushed the catastrophe at least a year later.

This will be a repeat of 2008-09, only bigger, when it finally hits, he was quoted saying to the publication.

Robert Prechter, author of Conquer the Crash, has also given his testament on the impending crash.

Prechter, who is also a stock market analyst, talked of today's economy which, as he says, has striking similarities to that of the Great Depression. The analyst believes that the U.S. stock indexes, including the Dow Jones and Standard & Poor's 500, will collapse. It will be worse than what happened during the financial crisis in 2009.

So what advice do these renowned experts have to offer in the face of a financial threat?

According to the report, Dent recommends buying short-term U.S. Treasury bills and the U.S. dollar, which will benefit from safe-haven cash flows.

Prechter believes it helps stock up on supplies and be prepared for such scenarios.

Celente recommends investing in gold if the value of the dollar goes down. He also advises moving out to other countries with much stable economies. Celente appears to be predicting a near apocalypse, as he suggests buying a gun for protection in the face of desperate times.

According to the Daily Mail, the report comes at a time when Warren Buffett, CEO and chairman of Berkshire Hathaway, made a statement on purchasing stocks in the light of an improving economy.

The multinational conglomerate, according to the report, also stated that home sales have reached its highest reading in January.

Oil prices, on the other hand, are rising mostly due to the sanctions imposed on Iran. The Associated Press reported that prices dipped slightly Monday, but that retail gasoline prices are continuing to climb up.

Although the economy appears to be recuperating to some extent, apprehensions that the it will be caught in a death spiral continue to plague Americans who are desperately hoping for a better future.
