1. It's been interesting tracking the NOAA broadcasts
via wunderground.com as Irene moves along. Some of those areas are very familiar to me over the years. It really brings it home what's occurring as the NOAA reports come in. I was just listening awhile ago to a tornado in NJ to DE and on up to Phila. area.
THE PRELIMINARY WATER LEVEL AT THE CHESAPEAKE BAY BRIDGE TUNNEL HAS RECENTLY PEAKED NEAR THE RECORD LEVEL THAT WAS ESTABLISHED DURING HURRICANE ISABEL IN 2003.
A lot of people along the rivers got totally wiped out by the flooding at that 2003 level.
6. I hate to bring Global weather change into this
but the science predicts more unpredictable and harsh weather. This MIGHT, not that we will know for a while, a new type of storm in some ways dependent on increased energy in the atmosphere.
The science predicts that the increased energy will do weird stuff to weather systems.
