Hopefully, you’ve been taking steps to preemptively prepare for an approaching hurricane as discussed in Part 1 of our How to Survive a Hurricane series.

How to Survive a Hurricane – Part 1

It’s hard to imagine what it’s like to truly be in danger if you have never experienced it. It’s also easy to push off preparing for “worst case scenarios” when it comes to weather–I mean, what are the odds, right? While preparing for a storm may be a low priority item in your long to-do list, pushing it off can be a costly, sometimes tragic, decision. When a major disaster strikes, stories of survival come pouring through the media, but it doesn’t take a major natural disaster to put you in harm’s way. Florida finally got hit with its first hurricane...

HealthCast: Flooding and Human Health

Flooding is the number one severe weather-related killer claiming approximately 140 lives each year. More than half of all flash flood fatalities occur in vehicles. But other hidden dangers to human health, both immediate and prolonged, can occur well after the flood waters recede. Weather and Zika Virus In the aftermath of flooding mosquito outbreaks tend to occur. As of late August 2,517 cases of the Zika virus have been counted in the United States. Miami is already dealing with dozens of locally transmitted cases. Heavy rain can aggravate the problem by creating more temporary stagnant pools where mosquitoes like...

The Saharan Air Layer (SAL)

I’d like to tell you about a member of the weather family: The Saharan Air Layer, or SAL for short. SAL usually gets alot of attention this time of year (August) as weather folk look toward the West Coast of Africa for tropical storm and hurricane development.  Now,  just like any other family member, SAL has both positive and negative qualities, depending on perspective of course. But to first understand SAL, we must first understand the geography and environment from which SAL originates: The Saharan region of Africa. In the equatorial tropics, the average wind is out of the northeast,...

2016 Perseids Guide

It’s that time of the year! Skywatchers rejoice! The Perseids are here and it’s predicted to be quite a show tonight. What are the Perseids? Every July and August, the debris field left behind by the Swift-Tuttle comet lights up our sky annually. Pieces of debris heat up as they enter Earth’s atmosphere and result in bright bursts of light. Most of the meteors are only the size of a grain of sand and burn up quickly. The Perseids event is considered the most popular meteor shower of the year and with good reason: it is the most active meteor...
