Frozen tsunamis, drought in Britain and review of a rare astronomical occurrence called the great syzygy       Send a link to a friend

Travel weather

West Coast weather woes: If your business travel plans have you flying in or out of San Francisco, Portland or Seattle, bring along a book or the extra laptop battery. Delays are almost assured, as stormy weather will mean plenty of rain and wind just about every day this week. Farther down the coast, Los Angeles will see rain early in the week, with delays likely to occur. Denver is shaping up nicely this week, with no rain or snow expected. The Chicago hub looks pretty good as well, with only a few midweek showers in the forecast. New York City, Philadelphia and Boston will start out cold, and a storm during the second part of the week will produce snow and rain. Quiet weather in the Southeast with no weather-related delays expected in Atlanta or Charlotte.

Alaska

Frozen tsunamis crash onshore: An occurrence not seen in three decades took place in Barrow, Alaska, in recent weeks, as huge ridges of Arctic Ocean sea ice crashed violently onshore. The ridges of ice, known as "ivus," act like frozen tsunamis and are among the Arctic's most feared natural phenomena. The larger of the two was 20 feet tall and over 100 feet long. The moving ice mountain crashed ashore and stopped about 30 feet short of a pump station that provides access to Barrow's underground water and sewer system. Strong winds coming eastward from out of Russia, along with eastward water currents, are being blamed for pushing the pack ice toward Barrow.

International

Britain faces water shortage: The worst drought that the country has seen in over a century has prompted warnings to Brits that if they don't start using less water voluntarily, rationing may occur in the near future. In the southeastern part of Britain, reservoirs are at less than half their capacity at a time of the year when they should be at or near full. Rainfall this winter has been the lowest since the disastrous drought of 1920-21. Even if rainfall returned to normal in the next few months, there would still be a serious problem in some parts of the country.

Roof collapse kills 52: A buildup of snow on a corroded and poorly maintained building is being blamed for the collapse of the roof over a busy market in Moscow. At least 52 people were killed and more are feared dead in the disaster, which occurred during the early morning hours last Thursday. Three inches of snow had fallen just prior to the collapse, on top of about 20 inches of snow that had fallen since the start of winter. The market was built in 1974 and designed by the same architect who drafted the plans for Moscow's Transvaal Water Park, where the roof collapsed in February 2004, killing 28 people.

Compu-Weather case of the week:
Out-of-this-world weather analysis

The company that operates a huge parking facility at the Croton-Harmon commuter train station north of New York City was being sued in small claims court. The plaintiff was the owner of a car that was damaged while parked in the lot on the day the flooding took place. While the amount in damage reimbursement being sought by the vehicle owner was relatively small at $550, there was concern by the parking lot company owners that if judgment was found in favor of the plaintiff, the floodgates could be opened for many other lawsuits, as over 1,000 vehicles had been damaged by water in the parking lot on that same day. Because of this concern, the owners of the parking lot brought in their attorney, even though the case was being heard in small claims court. Their attorney brought in Compu-Weather.

The big questions were these: Why did such terrible flooding occur in the parking lot, and was it something that the owners should have reasonably expected to occur and prepare for?

The forensic meteorologist assigned to the case prepared an in-depth analysis of the weather on the day of the occurrence, as well as the preceding day. What it showed is that a ferocious storm with very strong winds and heavy rain moved through the area. Rainfall for the two-day event amounted to more than 3 inches. A bad rainstorm? Yes, it was. But not bad enough to explain the extensive flooding that occurred.

Digging deeper, the meteorologist discovered that a rare astronomical occurrence had taken place on the very day of the storm. The occurrence was called the great syzygy, and it is an event that happens only once every few centuries. Six planets in our solar system were in alignment on that day, along with the moon. The result of this alignment was that the tidal flow in the Hudson River, which runs right next to the Croton-Harmon parking lot, was running extraordinarily high that day. This much-higher-than-usual tide, combined with strong west winds on the backside of the storm, pushed water toward the east bank, causing water from the Hudson River to come up and over the embankment between the river and the parking lot. That, on top of more than 3 inches of rain, produced the flooding.

The report prepared by Compu-Weather was presented as evidence at the hearing. Based on the fact that what had caused the flooding to occur was so rare an event, it was deemed by the judge that the owners of the lot could not have reasonably planned for such an occurrence to take place. Thus, they were not held liable for the damage that occurred to plaintiff's car. In following months, several other suits against the owners of the lot were heard, and each time the verdict was for the defense.
