Dangerous surf, flooding rain and potentially damaging winds are in store for Hawaii with the arrival of Tropical Storm Flossie.

Tropical Storm Flossie is expected to pass over or in between the northern tip of the Big Island and southern Maui Island on Monday.

After undergoing some weakening, Flossie will either be a minimal tropical storm or a depression at that time.

Not since Hurricane Iniki from 1992 has a hurricane or tropical storm reached Hawaii.

8.6 Million Times A Day

8.6 Million

That's how many times, on average, lightning strikes the Earth every day. That's about 100 times each second.

According to a 2004 study by lightning researchers, Dr. E. Phillip Krider and Kenneth Kehoe, the U.S. alone is hit about 30 million times each year by lightning.  

With temperatures up to four times as hot as the sun (up to 50,000 degrees Fahrenheit), concentrated into a channel often as slender as a pencil, it's no wonder lightning can be destructive and deadly.

Warm Weather Blamed for King Salmon Die-Off

King salmon in Issaquah Creek in Issaquah, Wash.

About 1,100 king salmon died returning to a hatchery in Southeast, and officials suspect the cause was warm weather.

KFSK reports the fish died sometime last week at the Blind River rapids on southern Mitkof Island, south of Petersburg. The fish were returning to the Crystal Lake Hatchery.

Alaska Department of Fish and Game sportfish biologist Doug Fleming said he found the dead fish after last week's warm weather, when temperatures were in the 80s.

He suspects a combination of factors led to the die-off, including hot water, low oxygen levels in the water and a large number of fish trapped at Blind Slough.

Fleming says they were expecting 1,800 adult kings to return this year. Officials will have a better estimate later this year of how many survived.

Tropical Storm Dorian Struggling in the Atlantic

Tropical Storm Dorian is fighting to maintain itself as a tropical cyclone.  Dorian, the fourth named Atlantic storm of the season, formed over the far eastern Atlantic Ocean southwest of the Cape Verde Islands early Wednesday morning.

Dorian will continue tracking west or west-northwest over the next several days on the south side of the Bermuda-Azores high, and will remain over open waters through the weekend.  

Dorian will approach the longitude of the northern Leeward Islands, the Virgin Islands and Puerto Rico Sunday night into Monday, and then the Dominican Republic and Haiti Monday night into Tuesday. While it appears more likely Dorian's center will track north of those locations, some fringe effects are possible in these areas, such as bands of locally heavy rainfall and areas of high surf/rip currents.

 

That all said, two factors are working to weaken Dorian.
