Taking a day off from the t.v. side Mon. but will be forecasting via WOKV 690 AM & now 104.5 FM.  You'll be able to hear the updated First Alert Forecast each & every day on WOKV!

This blog will be updated Tue....."Talking the Tropics With Mike" is updated every single day during the hurricane season -- click ** here ** .... click ** here ** to download the First Alert Weather iPad App.

A weak cool front will move into Northeast Fl. Sat. helping to trigger scattered heavy showers & storms. Storm cells will move southeast at 10-15 mph. So morning sun will have a tendency to quickly give way to storms -- keep an eye to the sky.

Onshore east winds Sunday will bring slightly cooler temps., especially at the beaches. There will still be enough moisture for at least scattered showers.

The following week will be dominated by moderate to -- at times -- gusty onshore flow. Scattered morning showers will occur near the coast transitioning inland through the day. Temps. won't be as hot ranging from the mid 80s at the beaches to near 90 well inland.

Earth Gauge: National Preparedness Month 

From extensive drought and heat waves to tornadoes and Superstorm Sandy, the United States experienced 11 weather and climate disasters in 2012, each with losses in excess of one billion dollars. 2013 has been no stranger to extreme weather and climate conditions either, with major winter storms in the Northeast and Midwest, tornadoes in the Great Plains, persisting drought conditions and historic wildfires in the West, record-breaking heat in Alaska, and major flooding in the Midwest.

Are you ready? September is National Preparedness Month – the perfect time to make sure you have the supplies and information you need to stay safe if extreme weather or another emergency occurs where you live.

Climate Fact: State of Knowledge about Heat and Cold Waves, Floods, and Droughts 

The scientific community has observed that extreme weather and climate events in the United States are changing over various time scales. Extreme weather events impact human health, agriculture, the economy and nature. The causes of changes in heat waves and cold waves are better understood than floods and droughts, because changes in river flooding are a product of intermingling factors and droughts are difficult to define and measure. Some of the observation highlights and trends are:

Heat Waves and Cold Waves

  • Heat is the number one weather-related killer. When heat is combined with high humidity it exacerbates the impacts of heat waves on humans, especially in urban heat islands.
  • The highest number of heat waves at a national level occurred in the 1930s, followed by the 2001-2010 decade; however, the western regions of the United States (including Alaska) had their highest number of heat waves in the 2000s.
  • The number of cold waves was highest in the 1980s and lowest in the 2000s. There has been a prevalent lack of cold waves in the 2000s.
  • North America’s coldest air masses from artic and subarctic Canada are warming.

Floods and Droughts

  • Most of the United States shows almost no change in flooding magnitude, with some exceptions. Flood magnitudes decreased in the Southwest and increased in parts of the Midwest, the northern half of the eastern prairies, and from the northern Appalachians to New England.
  • Days with heavy precipitation have increased in the eastern United States, especially in New England. Total precipitation for the United States has increased about five percent over the past 50 years.
  • Snowpack is melting earlier and affecting the rain-to-snow ratio in some regions of the U.S.
  • Droughts of the 12th and 13th centuries exceed those in the 20th century in duration and spatial extent.
  • Records over the past century indicate a general drying trend across the western United States in the past 50 years (1959-2008) compared to the previous 50 years (1909-1958).

Climate in the News: “Climate Change Leaves Hares Wearing The Wrong Colors” – NPR, September 8, 2013 The effects of climate change often happen on a large scale, like drought or a rise in sea level. In the hills outside Missoula, Mont., wildlife biologists are looking at a change to something very small: the snowshoe hare.

Have a great & safe weekend!
