Tracking Dangerous Hurricane Idalia

Hurricane Idalia will probably come ashore over the lightly-populated Big Bend area of the Florida Panhandle, the first Cat 3+ storm there since 1950. A quiet week is on tap for Minnesota with a little smoke but no drama. A full-blown, late-summer heatwave is brewing with 90+ highs Friday into at least the middle of next week. In theory upper 90s are possible by Labor Day. So much for easing into autumn. Check the blog for more details. -Todd Nelson

Tracking Idalia in the Gulf of Mexico

The National Hurricane Center starting issuing advisories for Tropical Depression TEN midday Saturday. By Monday, Tropical Storm Idalia had developed and is expected to continue to strengthen before making landfall along the Florida coastline as a possible major hurricane around midweek.

Tracking the Tropics

This system is expected to drift north into the Gulf of Mexico, while intensifying into a major hurricane before making landfall somewhere in the Big Bend area of Florida, where Hurricane Warnings has been issued. Tropical Storm Watches have been posted along the east coast of Florida, Georgia and South Carolina

Heavy Rainfall Ahead

Regardless of how strong this storm gets, heavy rain will be one of the main concerns here. Widespread 3" to 6" of rainfall be possible from Florida through the Mid-Atlantic States with some spots possibly seeing as much as 6" to 10", which could could cause flooding.

Gusty Winds Expected

Idalia is expected to reach the Florida coastline as a major hurricane with winds of nearly 120mph. This could certainly cause major damage and widespread power outages along with life-threatening storm surges.

Life-Threatening Storm Surge

According to NOAA's National Hurricane Center, the biggest storm surge could reach 8ft. to 12ft across parts of Florida's Big Bend. Tampa could actually see 4ft to 7ft surge as Idalia passes to the north.

Major Hurricane Franklin

Meanwhile, Hurricane Franklin was a major category 4 storm with winds up to 145mph on Monday. Franklin was a very impressive looking storm with a definitive "eye" as seen by the IR satellite loop below.

Flying Through The Eye of Franklin

Believe it or not, pilots and researchers from NOAA actually fly through tropical system, including major hurricanes! Take a look at the video below from a recent flight through Hurricane Franklin... unreal!

Tracking Franklin

As of Monday, Franklin was a major hurricane with 145mph sustained winds. This storm is expected to steer north of Bermuda (thankfully), but Tropical Storm headlines have been posted for the Island as rain, gusty winds, storm surge and life-threatening rip currents will be possible.

Active Weather in the Atlantic

As of Monday, the National Hurricane Center as tracking Hurricane Franklin and Tropical Storm Idalia in the Atlantic basin. There was also another wave near the western tip of Africa that has a moderate chance of development over the next 7 days.

Atlantic Basin Climatology

Our recent uptick in the Atlantic tropical activity coincides with climatology, which suggests that things ramp up pretty quickly during the 2nd half of August and into September. This is when the sea surface temperatures are typically the warmest in the Atlantic Basin. Note that the actual peak of the season is on September 10th, which is less than 3 weeks away. With that being said, the next several weeks could be pretty active in the Tropics.

Minnesota State Fair Weather

"It's time once again for the "Great Minnesota Get Together." Weather plays quite a role in the State Fair experience. Who doesn't remember braving the heat with the crowds on one of the busier intersections on a sweltering afternoon? A quick rain burst will send people scurrying for cover, and folks savor balmy days in the 70s with just a bit of a breeze. Below are some State Fair weather facts and notable weather events that have happened in past Minnesota State Fairs. Quick History of the Minnesota State Fair The Minnesota State Fair has been held at its current site since 1885. Before that it was held at a variety of locations including Fort Snelling. There were some years when the Fair was not held because of war, disease, or for logistical reasons. These years are: 1861 (Civil War), 1862 (Civil and Indian War), 1893 (Columbian Exposition), 1945 (fuel shortage because of WWII), and 1946 (outbreak of Polio.) In 2020 the fair was not held due to COVID 19. Beginning in 1975, the fair has a 12-day run each year ending with Labor Day. Thus since 1975, the Fair begins on a Thursday in August. Before 1975, the Fair was held for shorter durations (eleven days from 1972 to 1974, ten days from 1939 to 1971, eight days from 1919 to 1938 and six days from 1885 to 1918). The 2023 Minnesota State Fair runs from August 24-Sepember 4."

Tracking Dangerous Hurricane Idalia
By Paul Douglas

I live in a state of perpetual paranoia. If you're a meteorologist you sure don't want to miss a blizzard or a flood. But our version of the Super Bowl is hurricane landfall. Who will be impacted and how bad will it be? Give us a few days of lead-time to lower risk and move people to safety.

Hurricane Idalia will probably come ashore over the lightly-populated Big Bend area of the Florida Panhandle, the first Cat 3+ storm there since 1950. But the wind field around this dangerous storm is enormous, and parts of Tampa Bay may see tides rise 4-7 feet as the storm pushes north. Tell friends in the Tampa area to take this seriously and listen to local authorities.

A quiet week is on tap for Minnesota with a little smoke but no drama. A full-blown, late-summer heatwave is brewing with 90+ highs Friday into at least the middle of next week. In theory upper 90s are possible by Labor Day. So much for easing into autumn.

The pattern isn't favorable for significant rain. Hoping for a change in the weather.

Moon Phase for August 29th at Midnight

0.8 Days Until The Full "Blue" Moon

"Aug. 30 at 8:36 p.m. CDT - The second full moon occurring within a calendar month is usually bestowed this title. Although the name suggests that to have two Full Moons in a single month is a rather rare occurrence (happening "just once in a . . . "), it actually occurs once about every three years on average. There is actually a second and more arcane definition of a Blue Moon, apparently conceived by an almanac editor based in Maine back in the 1930s, but we will not get into this here. In addition, the moon will also be at perigee at 12:00 p.m. EDT., at a distance of 221,942 miles (357,181 km) from Earth. Very high tides can be expected from the coincidence of perigee with full moon (referred to as an astronomical spring tide). Finally, a full moon occurring very late in August or very early in September is sometimes bestowed with the title of Fruit Moon or Barley Moon. This will be the case with this second August full moon in 2023."

Climate Stories

(NOAA/The Minnesota Star Tribune)

"Opinion Wildfires move a mile a minute. The U.S. can't ignore the warnings"

"Maui officials should have known what was coming. In 2014, they were put on notice that highly flammable invasive grasslands presented a serious wildfire risk. In 2018, after West Maui fires destroyed 21 houses and 27 cars, angry residents criticized the poor disaster response. The next year, wildfires charred five times more land in Maui County compared with the previous year, and Hawaiian Electric admitted it needed to better fortify its power lines. In 2021, another report came out urging officials to clear flammable grasses. Again and again, the warnings came. Days before the deadliest U.S. wildfire in more than a century, weather forecasters warned that fierce winds would give life to dangerous fire conditions across much of the island, offering still more time to coordinate potential evacuation plans. As the fires barreled toward neighborhoods, officials failed to activate its expansive All-Hazard Statewide Outdoor Warning Siren System, instead opting for digital and radio communications many residents say they never got. At least 115 people have died, and more than 300 are missing. In the aftermath, leaders said "nobody saw this coming," but that is wrong."

"Scientists Design a Colorful New Paint That Could Cut Your Electricity Bill"

"Scientists at Stanford University have designed a new paint that could help reduce our growing reliance on air conditioners and heaters. It comes in an array of colors, and if used properly, it could seriously slash electricity bills and emissions. The paint is capable of reflecting up to 80 percent of mid-infrared light from the Sun, which is 10 times more reflection than conventional colored paints. Mid-infrared light is usually absorbed as heat on building surfaces. When used on the outside of a building, the paint keeps heat out, and it can be used on the inside to keep heat in. As such, the developers of the paint say it provides a "year-round energy-saving solution" that can be used in a variety of climates. When tested in artificially warm conditions, the paint reduced the amount of energy needed to cool the enclosed space by almost 21 percent. Tested in artificially cold conditions, it reduced the energy needed to heat the space by 36 percent."

"Study finds heat waves are becoming more frequent and more deadly"

"The risk of fatal heat waves has risen sharply over the past 20 years. In the future, such extreme weather will become more frequent and heat-related excess mortality will increase. Europe will be particularly affected, as ETH Zurich researchers show. Heat waves of the kind we are currently experiencing are particularly deadly for the elderly, the sick and the poor. The 2003 heat wave, which saw temperatures in Europe reach 47.5°C, was one of the worst natural disasters of recent decades, claiming an estimated 45,000 to 70,000 victims in the space of a few weeks. Forests burned, crops withered in the fields and emergency wards in the cities were full to capacity. Globally, costs totaled around 13 billion US dollars. Nevertheless, the public remains less aware of the risks of heat waves than of other climate-related extremes. This is a problem, as a study published in the journal Nature Communications points out. Heat waves like the one we saw in 2003 could become the new norm in the coming years."
