~~~ Hawaii Weather Narrative ~~~

Honoring Memorial Day!

The trade winds will strengthen into Tuesday, reaching moderate speeds…then fade away to some degree again this coming weekend. Here’s the latest weather map, showing moderately strong high pressure systems north-northwest and far northeast of Hawaii. At the same time, there’s the tail-end of a weak cold front moving over the eastern islands. Look for the return of trade winds into Tuesday, which will become locally quite gusty. The models are suggesting that these trades may ease up again Friday into the weekend…which is certainly not typical for this time of year.

Here’s a wind profile…of the offshore waters around the islands – with a closer view

Here’s the Hawaiian Islands Sulfate Aerosol animated graphic showing vog forecast

A weak cold front will push moisture over the islands through Wednesday. While clouds and showers will be most frequent over windward areas, a few showers will spread to leeward areas.  Showers from this front have already passed across Kauai and Oahu. Maui County and the Big Island will get into the action…over the next day or so. We could see fairly numerous passing showers crossing the windward coasts and slopes for several days. In contrast the leeward sides will be drier, although a few showers may sneak over into those areas here and there on the smaller islands. As the winds ease up again by the weekend, we may slip into a convective weather pattern, with clear mornings giving way to afternoon clouds…and interior showers.

Marine environment details: A weak front over Oahu will continue to move down the island chain over the next few days. Moderate to fresh trades are expected to fill in over the state and the coastal waters as the front progresses. Moderate northeast winds are already being reported at Barking Sands and Lihue, on Kauai The current forecast does not have the winds reaching the small craft advisory threshold. However, some of the more typically windy areas will be monitored…as they may see winds nearing this level.

The current southwest swell continues to hold, with the Lanai buoy reporting just above 2 feet surf. This swell should gradually decline into Tuesday before another small southwest swell bumps surf up late Tuesday into Wednesday evening.

A small northwest swell is slowly arriving and a bit undersized by this afternoon. This small swell will then decline into Tuesday, with no other swells on the horizon.

Here on Maui
– Early Monday morning is dawning mostly clear. Here at my place in upcountry Kula, it’s calm and clear…with an air temperature of 49.4F degrees at 540am. Meanwhile, at about the same time, the Kahului AP was reporting clear skies, with an air temperature of 65 degrees, 66 at Maalaea Bay and out in Hana…and the summit of the Haleakala Crater was 45 degrees.

Monday afternoon, under partly cloudy skies…and generally quite nice in most areas. My friends Bob, Tia, and I drove up the summit of the Haleakala Crater this morning. We walked down Sliding Sands trail and good distance, before just sitting down and listening to the great silence. The weather got cloudy with a bit of drizzle for a time, although it was nice enough. We were lucky enough to see the Silver Swords blooming, which was wonderful. By the way, the trade winds are filling back into our area, which is a good thing. Satellite imagery shows this cold front not far away, and here in upcountry Kula, it’s getting breezy and looking more like showers aren’t that far away.

A broad area of low pressure located about 950 miles south of the southern tip of the Baja California peninsula is producing disorganized showers and thunderstorms. Environmental conditions are expected to be conducive for gradual development of this system, and a tropical depression is likely to form later this week…as the disturbance moves slowly west-northwestward.

What Are Nile Crocodiles Doing in Florida?
At up to 20 feet long and weighing a ton and a half, with the strongest bite in the animal kingdom, Nile crocodiles can pretty much devour anything they want to — including humans.

As you can guess from their name, these carnivorous crocs are native to sub-Saharan Africa, where they subsist on small hippos, zebras and other animals they catch and, in some cases, swallow whole.

“In many parts of Africa, humans are commonly preyed upon by Nile crocodiles; therefore, fatal attacks and consumption by these large predators are well-documented,” notes the U.S. Geological Survey (USGS).

Scary, right? And now Nile crocodiles are living in the wilds of Florida.

In a new study, using DNA analysis, University of Florida scientists discovered several Nile crocodiles in the wild between 2000 and 2014.

“The odds that the few of us who study Florida reptiles have found all of the Nile crocs out there is probably unlikely,” Kenneth L. Krysko, one of the study’s authors, said in a statement. “We know they can survive in the Florida wilderness for numerous years, we know they grow quickly here and we know their behavior in their native range, and there is no reason to suggest that would change here in Florida.”

How did Nile crocodiles end up in Florida, more than 7,800 miles away?

Some were imported legally and are on display in tourist attractions like Disney’s Animal Kingdom. But the ones found in the wild had likely been brought here as hatchlings by smugglers in the exotic pet trade. The DNA analysis found that three of the Nile crocodiles were related.

“This is a very big predator, and now we’ve introduced it into Florida,” Krysko told the New York Times. “This is not a good thing.”

Nile crocodiles have previously been found elsewhere in the United States. Five of them escaped from a Mississippi alligator farm when it was flooded during Hurricane George in 1989, according to the USGS. But the DNA of the Nile crocs in the Florida wilds did not match that of those in any U.S. zoos.

Because of the exotic pet trade and the state’s subtropical climate, Florida is home to the world’s largest number of invasive species, including the Burmese python and Cuban tree frog, which have wreaked havoc on the ecosystem.

To prevent the Nile crocodiles from causing similar destruction, the University of Florida researchers urged state and federal wildlife agencies to capture and transport protected species out of their native range in order to quickly remove the Nile crocodiles.

This seems like quite a challenging task. Another challenge is being able to distinguish Nile crocodiles from native species. Along with being larger and more aggressive than the American crocodiles in Florida, Nile crocodiles are dark green or black rather than a lighter olive green. The tops of their heads are smooth instead of having a ridge down the middle. But to the untrained eye, these differences may be difficult to spot.

“We recommend the USFWS require a clearly identifiable photograph of a nonnative crocodilian before authorization for lethal take is granted,” the study advised. Good idea.

If these predators aren’t removed, it could be disastrous for Florida’s ecosystem. Fortunately, there have been no signs that the Nile crocodiles are reproducing – yet.

“My hope as a biologist is that the introduction of Nile crocodiles in Florida opens everyone’s eyes to the problem of invasive species that we have here in our state,” Krysko stated. “Now here’s another one, but this time it isn’t just a tiny house gecko from Africa.”
