Very dangerous situation for TX and perhaps even LA! Hurricane intensity appears imminent for Harvey (60 mph at 7 am CDT and just found to have complete eyewall structure). It is primed for rapid intensification thanks to light shear, warm waters, and now a stable inner core structure. Look how it was now 24 hrs ago compared to now! It looked much the same last night compared to 24 hrs ago!
This system will make landfall as a hurricane and an elevated risk exists of a major hurricane landfall. I’ll defer to the NHC for that as their updated forecast will be out very soon…2-4 ft of rain based on consistent model predictions and dangerous storm surge (increasing with increasing category) are a certainty. Be ready to evacuate and rush preparations to completion now!
Edit at 10:25 am:
Tropical Storm #Harvey is now forecast to become a major hurricane by landfall by the National Hurricane Center. At least at Category 3. It’s been 4322 days since Category 3 winds have impacted the US (Wilma in Florida) and 4352 days for the state of Texas (Rita). So destructive wind and saltwater coastal flooding is likely in addition to catastrophic freshwater flooding.
The biggest story with this system, regardless of its intensity at landfall. Some computer models indicate the potential of up to 2 FEET of rain along portions of the TX Coast this weekend with intense amounts of rain possible for portions of LA as well. Very heavy rain is possible inland from the coast as the tropical storm or hurricane may stall near the coast (because of high pressure over the interior of TX) with onshore flow pushing ashore very heavy rainfall rates.
If you know ANYONE in or within 100 miles of the TX Coast, tell them to watch the progress of this system. It’s extremely dangerous.
What an amazing event! The moon’s shadow gave a big show across America today and at 1:02 pm CDT it rushed over Lincoln, NE at over 1500 mph. Day turned to night, the temperature dropped and a 360 degree twilight ruled the midday.
The temperature in Lincoln dropped from 81 degrees around noon to 77 degrees after 1 pm and totality. Many locations along the eclipse path experienced temperature falls of 3-5 degrees as a result of the passage of the Moon’s shadow. Meteorologists also observed (both on the ground and with satellite imagery) the collapse of convective cumulus clouds dependent upon surface heating to “bubble”, which was lost during the advanced partial and total eclipses.
You can watch the progression of the Moon’s shadow across North America below (video is only four seconds long so you’ll have to replay to see it more than once at a time):
All I can say is that this was one of most spectacular events of nature I’ve ever witnessed. I’ve witnessed multiple total lunar eclipses and while they are spooky (especially in the middle of the night), nothing can beat the powerful changes which a total solar eclipse can bring to the landscape.
The clouds, which were the most problematic for eclipse viewing in Nebraska ended up breaking enough to see totality itself, but also provided a canvas for the incredible glow of midday twilight. It was quite magical.
The next total solar eclipse in the Lower 48 is April 8, 2024. Totality in parts of Texas (which will include Austin and Dallas/Fort Worth Metro) could last nearly 4 1/2 min compared to the 2 min 40 sec max with today’s eclipse. If time and finances align, I definitely want travel for that one if I don’t live near it by then.
Anyone have any eclipse experiences they want to share? I’ll be checking out WordPress posts too! 🙂
PS-A view from a Omaha news station of the twilight colors with clouds HERE (video) within totality near Beatrice, NE, south of Lincoln.
Consider this the final forecast and here on out its whatever Mother Nature decides. Overall looks great for the West (0-30% cloud coverage), deteriorates significantly over the Plains/Midwest (50-70%), improves back to low coverage over southern IL and TN (where totality will be at or near max possible), and deteriorates again over South Carolina.
Hoping for the best in Lincoln, Nebraska with 50-60% cloud coverage most likely transparent high clouds, however scattered opaque mid-level clouds are also possible which would diminish any serious solar viewing. My fiancé Cassie and I will head off to South Lincoln with our 1yr old and position ourselves at a location in view of the sun and the western sky (where the shadow will advance into town at 1500 mph). Whether we see the sun or on, it will turn to night at 1:02 pm CDT and last nearly 1 min 45 sec at our chosen location. We intend to have photos and I’ll also take video with my GoPro.
For 2017 Eclipse Coverage please follow me on Facebook or Twitter (see feeds on my main page for direct links). I will post on the progress of the eclipse on both platforms after the umbra’ landfall in Oregon at 10:16 PDT thru it’s exit from South Carolina after 2:50 pm EDT. Yes it’s only taking about a hour and a half for the umbra to blast across the US!
I will do a post-eclipse photo/video post hopefully by this evening or tomorrow for WordPress 😊
Anyone want to know what the 2017 Eclipse will look like at your location with nice graphics and all? Check out this excellent simulator put together by NASA’s Jet Propulsion Laboratory. You’ll be able to animate the eclipse for any given location in the US from beginning to end and find out what to expect. I made a collection of some of the locations which will experience partial eclipses (all at their time of maximum eclipse). All these location were in areas of 75% or greater obscuration of the solar disk. Optical and atmospheric effects begin to take hold with 75% obscuration as incoming shortwave radiation from the sun is significantly reduced. Read more about that in my previous July post HERE if you haven’t already. Remember, however, that even with 99% obscuration, the sun will still be too bright and therefore too dangerous too look at directly without certified eclipse glasses. Direct viewing of the sun for multiple minutes can blind you, any amount can cause eye injury!
The Great North American Eclipse is almost here! On Monday, the Moon’s inner shadow or umbra will touchdown over the open Pacific Ocean and rush toward a landfall in Oregon after 10:15 am PDT and exit the South Carolina Coast after 2:50 pm EDT. The shadow will be advancing across at around 1500-2000 mph. An incredible speed.
With the eclipse on Monday, the biggest concern is the weather…specifically sky conditions. The National Service, out of national interest in the eclipse (which will ONLY be seen in the United States) now has forecasts available, with special interest in sky condition forecasts.
Much of the eclipse path is *decent* (50% or less sky coverage forecast), although clear skies are extremely ideal. The best skies for totality are expected to be over the Northwest sector of the US, with greater cloud coverage (near 50% over the Central Plains/Missouri). There will be some improvement over Tennessee, but possible afternoon showers and thunderstorms may cloud up skies more significantly over extreme northeast Georgia and into South Carolina.
With that said…just remember…1) There’s more to the eclipse but totality! Regardless of whether you’re in the path or not, dealing with scattered clouds or not, enjoy the eclipse! Watch the crescents form in the shadows of trees, make a pinhole viewer (like this or this for example…I’m planning on making one!), if you have certified eclipse glasses or shades…safely observe the sun directly, and if you’re in a very deep partial (75%+) enjoy the effects of the weakening sun on temperature, sky and the animals. Also…2) For those in totality, all you need is that precious 1 or 2+ mins to be clear around the eclipsed sun. Hopefully, with that 50% or less sky coverage, that will be easier to achieve.
As you all may know, I live in Lincoln, NE…in the path of totality. As the city is literally on the northern edge of the shadow, there is a tight gradient for the length of totality; anywhere from tens of seconds on the north end of town, to 1 min 45 seconds on the south end of town. My house will see around 1 min 15 seconds. We had planned on going to Grand Island, NE about a hour and a half west of here to visit a relative of hers and see the eclipse at 2 min 35 sec (near max possible duration)…but our car has an issue which makes it not reliable for traveling on the highway! 😦 Literally found this out today! Extremely disappointed as there isn’t enough time for us to get the car fixed. But considering we’re still IN totality vs. not, I can’t completely complain. So instead, we’ll be heading to the south end for the maximum length in Lincoln. I’ll have my GoPro set up on a mini-tripod to capture very high-res video of the last minutes before totality and during it. My fiance and I will also take lots of photographs. I will have updates on my Twitter and FB pages as the partial eclipse advances toward totality (feeds also can be seen from the website…but please follow me directly! 🙂 ).
It should be an exciting day! Everyone have safe viewing and have fun!
