Then the barometer started dropping and the winds increased. At noon time it was down to 29.09 inches with a temperature of 82 deg. F. From 1:05 PM to 1:30 PM, it reached a low point of 28.73 inches and then gradually reached 28.76 inches at 2:00 PM, 29.01 inches at 3:00 PM, 29.38 inches at 4 PM until it went to 29.74 inches at 9:00 PM. During all of this time the temperature stayed constant at 82 deg.F.
Up to 1:30 PM the winds were probably around 100 mph with higher gusts but there wasn't much rain. Then afterwards the tremendous rains came and lasted for around 3 to 4 hours with winds probably in the same range as before. The great forces caused some trees to be uprooted, some roofs to leave the houses, and debris flying through the air like a snowstorm.
The eye of the hurricane was near this location but there was no defined calm area at the lowest barometric reading. It rained, sometimes heavily, during Monday night so that a damage assessment could not take place until daylight.
On Tuesday morning, the power was out all over the island and the phones at my location were down. Some phones were still in operation but the long distance service from St. Thomas to the States was out
which made it difficult for anyone to make a call off the islands.
At my location, no one was injured and there was no major damage. Water wet some of the floors and downed trees, branches, and parts of roofs littered the outside. It was reported that no one lost their life during the hurricane on St. Croix but 4 new babies were born during that time. Because we were well prepared, and because the winds were not has high as predicted, we were able to overcome any severe damage from this storm.
I originally uploaded this description to the website around 4 PM AST on Wednesday, September 23rd after I was able to find a local phone connection and the long distance services from the islands had been restored. Much of the island of St. Croix is returning to normal and I expect my personal phone and power to be restored later today. The school where I teach, St. Joseph High School, will resume operation on Monday, September 28th.
I intend to provide more detailed information regarding the barometric pressure changes during the hurricane on my website in several days.
Teachers and students should feel free to make use of the data to make graphs and as part of a study of an abiotic factor.
Below is the data which can be used as part of your lesson
plan. I would suggest that you have the students make a graph from
the data and then have them interpret the graph. I will post the graph from the first school to send me an accurate and complete line graph of all of the data points in the table. This should be in the form of a .jpg or .gif file of 300 kilobytes or less. Send an interpretation file with it in the email to which the file is attached.
