Beginning the hurricane season with a * bang *.  At this point, we should be thankful that it's not later into the season given "Andrea's" location & movement.  Statistically...a June named storm should only occur once every 2-2.5 years, but this is the 3rd year in a row with at least one named storm in the Atlantic Basin as early as June or even May.
For frequent & specific updates on "Andrea", click ** here ** - "Talking the Tropics With Mike".  Click ** here ** to download the "slick" First Alert Weather iPad App...send storm info. & rainfall amounts to: weather@actionnewsjax.com.

It looks like the worst of "Andrea" for the First Coast -- heavy rain & isolated tornadoes & waterspouts -- will be from the middle of the day Thu. through early Fri.  Conditions will rapidly improve through the day Fri. leaving us with a hot/humid weekend with the typical scattered afternoon thunderstorms aided by a sea breeze.

So here's the bottom line:

* Conditions will deteriorate from south to north through the day Thu. with a peak of the worst conditions from late morning/early afternoon
Thu. through early Fri.

* Primary threats will be heavy rain & isolated tornadoes/waterspouts

* Anyone living in a flood prone area, should stay alert.  Rainfall will average 2-4", locally as much as 6" sending the weekly total to as
high as 10"+ in a few spots

* Winds will average 15-25 mph over land areas with gusts of 25-35 mph.  Winds near & off the coast will reach 25-35 mph with gusts of 40+ mph.  Of course, any tornadoes/waterspouts will be capable of locally much higher winds.  Wind direction will be from the SE Thu...from the south Thu. night....becoming from the W/SW Fri. (offshore!).  While not usually damaging at these speeds, the saturated ground will make it easier for some trees to be uprooted.

* Seas will build to 5-7 feet by late Thu. subsiding Fri....surf will reach 4-6' by Thu. night...3-5' Fri.

* Conditions will rapidly improve Fri.

Global May Temps.......

As part of an ongoing joint project between UAHuntsville, NOAA and NASA, Christy and Dr. Roy Spencer, an ESSC principal scientist, use data gathered by advanced microwave sounding units on NOAA and NASA satellites to get accurate temperature readings for almost all regions of the Earth. This includes remote desert, ocean and rain forest areas where reliable climate data are not otherwise available.

The satellite-based instruments measure the temperature of the atmosphere from the surface up to an altitude of about eight kilometers above sea level. Once the monthly temperature data is collected and processed, it is placed in a "public" computer file for immediate access by atmospheric scientists in the U.S. and abroad.
Global Temperature Report: May 2013

Global climate trend since Nov. 16, 1978: +0.14 C per decade

May temperatures (preliminary)

Global composite temp.: +0.07 C (about 0.13 degrees Fahrenheit) above 30-year average for May.

Northern Hemisphere: +0.16 C (about 0.29 degrees Fahrenheit) above 30-year average for May.

Southern Hemisphere: -0.01 C (about 0.02 degrees Fahrenheit) below 30-year average for May.

Tropics: +0.11 C (about 0.20 degrees Fahrenheit) above 30-year average for May.

April temperatures (revised):

Global Composite: +0.10 C above 30-year average

Northern Hemisphere: +0.12 C above 30-year average

Southern Hemisphere: +0.09 C above 30-year average

Tropics: +0.17 C above 30-year average

(All temperature anomalies are based on a 30-year average (1981-2010) for the month reported.)

Notes on data released June 4, 2013:

Global average temperatures and the tropics continued a slow cooling drift in May, downward from a warm January, said Dr. John Christy, a professor of atmospheric science and director of the Earth System Science Center (ESSC) at The University of Alabama in Huntsville.

Compared to seasonal norms, during May the coldest area on the globe was in northern Greenland, where the average temperature was as much as 3.75 C (about 6.7 degrees Fahrenheit) cooler than seasonal norms. Compared to seasonal norms, the “warmest” area on the globe in May was in the northern Siberia. Temperatures there were as much as 3.91 C (about 7.0 degrees Fahrenheit) warmer than seasonal norms for May.
