ICYMI Oct 22–October Snow/Warm Temperatures/Orionids

While we were basking in sunshine and temperatures in the upper 60s to near 70°, parts of the northeast saw an October Snow.

That photo was courtesy of NWS Burlington in Vermont.  As much as 3 to 5 inches of snow is expected, especially in higher elevations, in New York, Vermont and New Hampshire.

Closer to home here in Iowa, we had October snow…just 3 years ago.  In fact, one inch accumulated in Waterloo.

snow2


We are now toward the end of October, where high temperatures should normally be in the upper 50s to near 60°.  That wasn’t the case today.

There’s a good chance that the warmer than normal (or near normal) temperatures will continue through the end of the month.

Hurricane Andrew Anniversary

On August 24, 1992, Hurricane Andrew made U.S. landfall for the first time in south Florida. Just two days before, it strengthened quickly into a hurricane after it nearly fell apart in the central Atlantic Ocean. By the time Andrew made it to Florida, it was a Category 4 storm with sustained winds over 130 mph. Andrew tracked through the very southern tip of Florida and into the Gulf of Mexico. It moved northwest into south central Louisiana as a Category 3 storm on August 26. Andrew then began to track northeast toward the mid-Atlantic as it began to weaken.

AndrewTrackLandfall2

Ten days earlier, Andrew developed off of the western coast of Africa on August 14. It strengthened into a tropical depression on August 16 and earned the name Andrew once it became a tropical storm on August 17. For a few hours on August 23, Andrew sustained Category 5 status just prior to making landfall.

AndrewTrackFull2

Over its lifetime, Andrew caused $26.5 billion dollars in damage  – the majority in Florida – and 23 deaths. A deadly tornado in southern Louisiana was another result of the storm. Andrew is the fourth strongest hurricane (by pressure) to make landfall in the United States.2

The storm name “Andrew” has been retired by the World Meteorological Organization.
