Fall-Like Dewpoints This Week

Looking at the dewpoint forecast through the week ahead, it certainly won't be humid! As a big bubble of high pressure settles in this week, dry and mostly sunny weather will persist. Dewpoints will still be in the 30s on Wednesday, which will be some of the driest dewpoints we've seen so far this season. As the bubble of high pressure moves east, a southerly wind will help to boost temps and dewpoints over the coming days.

Vertical Evacuations In A Hurricane"
By Paul Douglas

I am reminded of a surreal chat I had with Steven Spielberg on the set of "Jurassic Park" in1991. He told me that filming on the Hawaiian island of Kauai was interrupted by Category 4 Hurricane Iniki in 1991. The hotel manager told them to seek shelter in the basement of the ballroom, on ground level (close to the ocean). I said, "Mr. Spielberg, in a tornado you want to be below grade, but in a hurricane the storm surge means you want to be high up off the ground, 3rd floor or higher." His eyes got big as he wandered off but that conversation haunts me to this day.

If friends and family from Ft. Myers to Sarasota can't (or won't) evacuate inland, encourage them to consider a vertical evacuation: a high-rise condo, hotel or office building. Hurricane Ian will strike later today, probably as a major Category 3 storm. Tampa Bay should avoid a direct strike.

Our dry holding pattern lingers with 70F by Saturday, maybe a string of 70s next week. We can't buy a shower.

Meanwhile parts of Florida may see 30+" of rain.

Climate Stories

(NOAA/The Minnesota Star Tribune)

"Electric cars charging at night could make America's power grids unstable, study warns"

"Leaving your electric car charging overnight to have it ready in the morning seems like a good idea in theory. But in reality, research suggests doing so does more harm in the long run. Stanford scientists say that it's more costly to charge your electric car at night and it could stress out your local electric grid. Instead, researchers suggest drivers should switch to charging their vehicle at work or in public charging stations. Another added benefit to charging in the daytime at a public station is that it reduces greenhouse gas emissions."

"NASA just crashed a spacecraft into an asteroid to see what would happen"

"A NASA spacecraft slammed into the surface of a distant asteroid at 7:14PM ET on Monday night, the climax of the agency's Double Asteroid Redirection Test (DART). An hour before impact, the target asteroid, Dimorphos, wasn't even visible in the images from the spacecraft. In some of the early images sent back to Earth, even Dimorphos' larger companion Didymos, looked like a single speck against a sea of black. The DART spacecraft was moving at 14,000 miles per hour, and details quickly came into view. Viewers on Earth saw the rough surface of Didymos zip by as the spacecraft cruised autonomously towards Dimorphos. Boulders filled the screen just before it went bright red, indicating a loss of signal — DART had reached its final destination."

"Despite sun's year-round presence, 2 in 5 think sunglasses, sunscreen only beneficial in summer"

"This one might leaving you scratching your head. Despite the sun's year-round presence, 39 percent of Americans — for some reason — mistakenly believe sunglasses are only for summer. A study of 2,000 Americans' awareness of how to take protective measures to keep their eyes and body safe also finds that, similarly, 40 percent believe sunscreen is only for the summer. While 72 percent of respondents are the most careful in the summer, slightly fewer (68%) claim they take protective measures every time they go outside – even if for a short period of time. For some, these measures include wearing sunglasses (62%) or staying hydrated (61%). For others, it's applying sunscreen (53%) or wearing clothing that covers their skin (51%)."
