Well, the tropics are heating up, as they usually do in mid-September and Invest 95L, an area of disturbed weather in the tropics just north of the SE tip of Cuba, near the Turks and Caicos, is forecast to have an 80% chance of becoming a tropical depression in the next 2-4 days.

None of the models show it being anything more than a depression or minimal tropical storm in the next 2-3 days, as it meanders across the Bahamas and towards the FL east coast, so major impacts to those areas are unlikely, but even heavy rain is not needed for the northern Bahamas, which were devastated by Dorian.

Some models are showing a tropical storm to even a hurricane in the 3-4+ day timeframe (although not all models show development occurring) with tracks anywhere from across FL and into the Gulf of Mexico (if the system remains weak and disorganized) to up the east coast of the US (if it strengthens more quickly), with a track out to sea off the coast possible, but less likely, as there is a strong Atlantic ridge ("Bermuda High") to the north of this system.

There is even a small chance of a TS/hurricane impacting our area by late next week into the weekend, depending on timing. If that were to occur, the weather for the BC game could be impacted, but it's way, way, way too early to speculate on that. As of now the long range look ahead for Days 6-10 (which includes 9/21) is for well above normal temps and well below normal precip, so warm and dry is more likely for the game than wet, but again too early for that.

And beyond that there is another tropical wave a few hundred miles SW of the Cape Verde Islands, which the NHC has as having a 40% chance of development into a named storm in the next 5 days, as it moves mostly westward and approaches the Lesser Antilles (Leeward/Windward Islands) and the Caribbean.

Way way way too early...but this afternoon’s model runs were disastrous for our area late next week. Yikes.
 
Next weekend, but again way toooo early to take seriously. Should never have posted...haha
It's why I would never post hurricane model runs past about day 6-7 - the inaccuracy is just way too high. It's probably a 1 in 100 shot to hit our area with even tropical storm conditions. Euro did show a similar solution last night, though, so it shouldn't be ignored, but model runs off of a storm that hasn't even formed yet are even more inaccurate, so let's wait until a storm actually forms before posting model runs. That's my advice anyway.

My wife and I are going to Cape May next weekend, so I'll follow your info closely!!

We now have "Potential Tropical Cyclone #9" - NHC says likely to be a depression or tropical storm in the next day or so and it's forecast to make landfall on the Central Florida coast around Saturday night as a modest tropical storm with winds in the 50 mph range; in addition, TS warnings are up for much of the northern Bahamas, where Dorian hit, for 5" or more of rain and TS force winds - not what those folks need.

The storm is then forecast to go inland and up the coast, reemerging into the Atlantic just off the Northern FL/Southern GA coast in 5 days. Beyond 5 days the models are all over the map, literally, with landfalls ranging from Mexico to Canada, including the US, of course. Obviously, uncertainty levels are fairly high with this storm, as one can see from the fairly large track cone and the model mayhem after Day 5.

The 2 p.m. cone has the storm heading out to sea after it hits Florida and Georgia. Maybe we'll be lucky again.

Hobbs just announced they are moving the game to Thursday to avoid hurricane Eduardo but it will move to ESPN
Hobbs just said the hurricane doesn’t interview well so it won’t impact the game next Saturday.

Tropical Depression #9 has formed in the SE Bahamas and is expected to become a tropical storm sometime tomorrow. The storm, which will be named Humberto, will, unfortunately, move across the northern Bahamas, which were hit by Dorian. While it'll likely only be a modest tropical storm for the part of its journey over the northern Bahamas, several inches of rain and 40-50 mph wind gusts won't help recovery (although fresh water is needed for the cisterns).

The good news after that is that the storm is now modeled to move further offshore of the Florida coast (75-100 miles offshore), so impacts are looking minimal, even though the storm will be strengthening, as it's forecast to become a Cat 1 hurricane by Monday/Tuesday, as it heads ENE towards Bermuda on Wednesday, likely staying well offshore of GA/SC/NC, which is good news for those states, too.

It is possible that the steering currents then break down and allow the storm to slow down significantly, meaning interests along the US east coast will still need to monitor the system for movement back toward the coast by late next week - way too far out to predict that, though.

As of 11 pm last night, we have Humberto. Track is even further to the east so the tropical storm watches were dropped for the FL coast and after some moderate impacts on the northern Bahamas, where TS warnings are up, Humberto is forecast to head ENE towards Bermuda, nearing that island on Thursday morning, as a Cat 1 hurricane with 80-90 mph winds. The chances of any impact to the US east coast are dwindling and near zero now.

Its likely to be sunny and quite warm next Saturday with highs 80-85

I hope that's right because my wife and I will be in Cape May. But (as you are often very quick to remind us) a week is a long time in weather forecasting. Let's see how the forecast looks in a few days.
 
Humberto is bearing down on Bermuda - will be a close call with hurricane watches up for Weds night/Thurs morning, as the storm is a Cat 2 and could become a Cat 3 on its approach to Bermuda - hopefully, the models are correct and it'll be a near miss with regard to high winds, but storm surge and rain/flooding will be an issue.

After that, watch out for Imelda and Jerry. That is, the just named tropical storm Imelda, which formed this morning close to the Texas coast, with flooding rains being its main impact over the next few day, and TD-10, which is likely to become Tropical Storm Imelda in the Central Atlantic shortly and which will threaten the Leeward Islands and possibly the Bahamas, likely as a hurricane by then, but hopefully this storm will go north of those islands and recurve out to sea, missing the US east coast.

So. Imelda just formed this morning and just made landfall in Freeport, TX with 40 mph winds. This storm is mostly a rain/flooding threat, especially as it will be moving very slowly dropping 5-10" of rain on many in that area (not a Harvey threat, but flooding is still likely), as per the graphic below.

And the future Jerry is in an area somewhat favorable for development over the next 5 days, as it's forecast to become a strong Cat 1 hurricane in the next 4-5 day, as it moves just north of the Leeward Islands and Puerto Rico; see the graphic below. Those locations are just inside the track cone, so direct impacts can't be ruled out, but they're likely to be spared major impacts if the forecast track holds and keeps the storm 100+ miles away.

Beyond that, around Day 5, the storm will be making its way a bit to the north of the SE Bahamas/Turks-Caicos, but those areas need to keep watch on this storm, as they're within the track cone, given the uncertainty in forecasts that far out. And then the storm is fairly likely to recurve N, then NE away from the northern Bahamas and US east coast, but that's 6-7 days out and forecasts aren't that accurate at this range, so interests in those areas need to pay attention.

And probably not a drop here in SA...but I can at least see the clouds as they rotate around Imelda’s center!



Local offices do a way better and more visually appealing set of graphics
 
Uusually - and they ought to be able to do better local graphics, since they're, well, local...
It really would not take much to make nationally appealing graphics...they just don’t...haven’t for a long time...clearly not a priority. The SA/Austin office is like an art school by comparison.

Well, Humberto hammered Bermuda with some heavy rains and high winds, but was not a direct hit and is heading towards the North Atlantic, while Jerry is now a hurricane, but looks like it'll miss the Leeward Islands, PR, and the Bahamas and head towards Bermuda. See the map below.

However, Imelda, by far the weakest (never had >40 mph winds) and shortest-lived of these storms (was only a TS for an hour or so), stalled the past 2 days and has put down close to Harvey level rainfall (20-35") in SE Texas, leading to life-threatening flooding from Houston to Beaumont. Fortunately, the heaviest rains are now over with.

Not as large of an area of torrential rains, compared to Harvey, but almost as much in a shorter timeframe in some locations - see the comparison map below. Just goes to show that often rainfall is the biggest impact from a tropical system, as it was for Harvey and Florence in recent years. Crazy.

Tell that to the two people who died today in floods in SE TX or the hundreds who needed water rescues. Another stupid post by our resident troll.
More of a result of poor land use and development. SE TX is a case study of what not to do regarding stormwater management and urban planning.

Every city could do better with land use/over-development, in particular, but name me anywhere that is "prepared" for 30" or more of rain in 36-48 hours, like much of SE TX got in Harvey and now Imelda. We get 10" of rain in our area and there is raging flooding.

We have a very active pattern over equatorial Africa (where tropical waves that become tropical storms/hurricanes often originate, especially in the August-September timeframe) and this is the first time I recall the NHC calling attention to a wave actually still over land in Africa (see the graphic below), although I'll admit I don't look at this graphic every day. I asked on the weather boards whether this has been seen before, but no response

Anyway, the NHC has a 70% chance of formation over the next 5 days, which is presumably very high for a system that is over land. Nothing to worry about for at least 10 days for anyone in the Caribbean or beyond, but thought this was interesting.

In addition, Invest 99L about 500 miles from the Windward/Leeward Islands, is now listed as having a moderate chance of development into a named system over the next 5 days, although conditions aren't favorable for strengthening beyond that in the Caribbean (but that's too far out to be sure of).

Finally, Hurricane Jerry will miss the Leeward Islands/Bahamas and recurve to the NE and take aim at Bermuda in about 5 days as a likely Cat 1 hurricane. Bermuda is used to these.

And really finally, below is a graphic showing the incredible rainfall from Imelda in SE Texas - not as widespread as Harvey, but just about as much for the Houston-Beaumont regions. Also, the first link below has some fairly convincing analysis that these extreme rainfall events are likely to be at least partially due to global warming and that we're likely to continue seeing more extreme rainfall events in coming years. That's going to become an interesting discussion in the next few years...

Our highly active September - climatologically the most active month for tropical activity, by a decent margin - continues with Jerry, Karen and Lorenzo all currently named storms, bringing the season total to 12, so far (a normal season would have 8 by now). Will have to check in on the seasonal thread. Some highlights...
  • So, Jerry is now a strong tropical storm and will come within about 100 miles of Bermuda tomorrow morning, but should not be direct hit, and will then move into the Central Atlantic and dissipate. Jerry is mostly a rain threat for Bermuda, unlike Humberto last week, which had its eyewall come ashore, although the center did not, so it wasn't a landfall - but an 82 mph sustained wind was recorded with gusts over 100 mph and 80% of the island lost electricity (but no lives lost).
  • Karen, which formed a few days ago near the Leeward Islands, but has struggled with high shear in its journey northward through the Caribbean, finally regained TS strength today and is currently lashing Puerto Rico and the Virgin Islands with 40-50 mph winds and heavy rains, with flooding likely. Karen should move away from those islands overnight and then move northward and then stall as it hits a strong ridge (high pressure) in the SW Atlantic, but Karen should also strengthen some (to 60-70 mph by days 4-5). Whether or not it is then sent westward by the ridge, beyond 5 days or just kind of meanders about ~500 miles north of PR, is an open question. Interests in the Bahamas, Florida and US east coast need to watch this system, as some model ensemble members have the storm headed in that direction in about 10 days, but many have the storm looping around and/or curving out to sea. Way too far out to predict accurately.
  • Finally, that wave off the African coast from several days ago formed Lorenzo on Monday morning SW of the Cape Verde Islands and while Lorenzo is forecast to become a major hurricane, its track is very likely to be a "fish storm" heading NW and then N into the Atlantic far from any land mass or islands.
  • One more interesting tidibt. The remnants of Lorena, which came ashore on Mexico's Baja Peninsula, are now soaking large parts of the desert SW with heavy rains

Jerry's gone, Karen is in the process of being sheared to pieces and will be downgraded to a remnant low in the next day or two and won't be a threat to anywhere, while Lorenzo has become tied (with 1989's Gabrielle) for the most powerful hurricane ever in the Central Atlantic, with Cat 4 winds of 145 mph. This huge, powerful storm is fortunately not a threat to land, other than the Azores in about 5 days, when the storm will likely be just a weakening Cat 1 hurricane, if that. Beyond that, no more obvious tropical systems in the pipeline, as we near the end of September. There's still often activity through October and into November, though...
