Hurricane Lane, and Interesting Images

Hurricane in Hawaii

Hurricane Lane, while not making landfall directly on Hawaii, has certainly made a huge impact on the state with extraordinarily heavy rains and catastrophic flooding. Some areas of the island of Hawaii have received nearly 40 inches of rain, and mudslides have occurred in a number of locations. Tropical storm force winds have also affected several islands.

Although the storm’s effects have been significant, as can be seen in this story from, because the hurricane weakened as it approached Hawaii, the state was spared greater devastation and loss of life.

What’s in our air?

NASA’s Earth Observatory released pictures yesterday depicting some of what we are breathing in every day. From carbon in smoke from fires, to sea salt to dust and sand, there are many elements to our air than just air. It is a fascinating look at the different elements that arise, both naturally and unnaturally from events on the land and sea that influence the air we breathe and have impacts on health.

Humid Pattern Continues

If you live in the Eastern half of the United States, you have certainly noticed by now that this summer has been conspicuously damp. A persistently humid pattern has stayed stubbornly rooted over the region, particularly along the coastal states. The meteorological culprit has been the presence of a blocked pattern in the atmosphere – high pressure out over the Western Atlantic Ocean ( a so-called Bermuda high, given it’s location) and low pressure over the Midwest – has caused a consistent flow of air from the Gulf of Mexico and Atlantic Ocean over the Southeast, Mid-Atlantic and New England.

As a result of this pattern, the kind of summertime weather conditions usually seen over the Southeast have prevailed over most of the Eastern US. The map below, courtesy of Intellicast (, depicts the amount of rainfall received in just the past week, and shows the kind of “marbling” often seen in just the Southeast, where it is common for pop-up thunderstorms to develop and move slowly. This has happened more commonly this summer and over a larger area.

Many areas in the Eastern US have already received 30+ inches of rain for the year (

The persistently high humidity levels can have significant and dangerous effects on people. High levels of moisture in the air make it significantly harder for your body to relieve heat. Because your body has to work harder to sweat, high humidity levels cause tiredness and can lead to dehydration, muscle cramps, heat exhaustion and eventually, heatstroke. Take care in these conditions by spending as much time as possible indoors inside air conditioned rooms.

This pattern generally looks like it will last for at least another 10 days or more, but should begin to subside as we get closer to the end of August.
