Water vapor of Tropical Depression 8.
It is a 'normal/cyclonic' storm that is very well formed already at a relatively high central pressure or 1007. It has a great deal of potential to become big and bad. The 'thing' about hurricanes/tropical depressions in a Human Induced Global Warming troposphere is that 'pressure' and 'temperature' are related. They are complimentary to each other when it comes to increasing velocity of winds of these storms.
Example: Boiling water. It boils at 212 F. Right? But did you know you can boil water at 98.6 F? It is possible IF the pressure is very high. In other words as the temperature of the Earth reacts to the pressure of Earth, there will be higher velocities in an environment that is 'stacking' it's temperature at higher altitudes.
Seeing the well formed central eye of the storm at such low pressure brought to mind the 'idea' that as the troposphere is hotter at higher latitudes it may very well change the column of air we call 'normal' at sea level to allow higher velocities. See the column of air would be less at higher temperatures EXCEPT with super hot air 'trapped' without molecules allowed to expand in volume, the actual velocity of the air molecules 'seeking expansion' under hotter climatic conditions will actually accelerate. So it may be why there is far more damage to these systems than one would 'traditionally' expect under the same temperatures and 'normal sea level pressure.'
Think of it this way. When putting a limited amount of water in a tea kettle and then heating it to boiling; the 'normal' state of the tea kettle would be to allow the increased pressure due to expanded capacity of the water vapor out the spout and the kettle sings. But. What if that kettle had no spout and was sealed without the ability to allow the steam out. What would happen? It would explode. The water would completely turn to vapor and become so hot with molecules moving very fast that the pressure due to the space between the molecules would test the tensil strength of the metal teapot. Same thing with the troposphere. The heated water vapor, where it exists, expands without any place to escape under carbon dioxide 'heat' and that manifests in water vapor with 'enhanced' velocity.
Eighth and ninth depressions forming (click here)
The eighth tropical depression of the hurricane season is forming about 1,100 miles east of the Lesser Antilles. The storm is moving west-northwest around 12 miles per hour with maximum sustained winds near 35 mph. A National Weather Service advisory reports the storm is expected to continue on its northerly track, decreasing in speed during the next 24 hours. A ninth depression is also forming along the northwestern Gulf of Mexico along the Texas coast. Tropical storm warnings are issued for Port O'Conner, Texas to Cameron, La. The depression is moving north near 6 mph with maximum sustained winds of 35 mph. Rainfalls, according to a NOAA advisory, are expected between 5-10 inches with extremes along the middle and upper coast of Texas and lower southwestern Louisiana. The depression is expected to reach tropical storm status prior to making landfall.
Just as a point of reference when a storm 'spins' 'anticyclonically the 'normal definition is that is a 'high pressure spin.' The odd aspect to the last storm that made landfall in North Carolina, "Gabrielle,' is that it was supposed to have a low pressure center as it was called a Tropical Storm. However. There is no official measure of it's 'central pressure' I have noted yet. I don't know if there is anyone other 'Tropical Storm' on record that NOAA/NASA/The National Weather service hasn't provided a central pressure as a matter of record. Very odd.

Water Vapor of Humberto as a 'normal/cyclonic' storm for the Northern Hemisphere.
This is Humberto in Water Vapor Satellite. Louisiana and New Orleans will get some rain from this storm. Certainly it's something manageable by the levees. This storm does not have the potential to cause all that much trouble.
TD 9 becomes Tropical Storm Humberto (click here)
Tropical Depression 9 has gained strength and is now Tropical Storm Humberto.
A tropical storm warning remains in effect from Port O'Connor, Texasto Cameron. La. A tropical storm watch remains in effect from east of Cameron to Intracoastal City L.
At 1 p.m. the center of Tropical Storm Humberto was about 70Miles south-southwest of Galveston, Texas and about 145 miles east-northeast of Corpus Christi, Texas.
Humberto is moving toward the north near 6 mph and this general motion is expected to continue over the next 24 hours. On the forecast track, the center of Humberto should be crossing the Texas coast within the warning area tonight.
Maximum sustained winds have increased and are now near 45 mph with higher gusts. Some additional strengthening is possible prior to landfall. The earlier air force reserve unit reconnaissance aircraft returned to base for mechanical reasons, but a second aircraft is expected to reach Humberto within an hour or so.
The next advisory will be issued by the National Hurricane Center at 4 p.m.

UNISYS Enhanced Infrared Satellite.
Most of North America is under a high pressure system but there is some trouble brewing. Tropical Storm Humberto is offshore of Texas and Louisiana and they know it. Even the New Orleans paper is monitoring this and the tropical depression in the Atlantic which more than likely will pick up velocity once in reach of the Lesser Antilles.
The high pressure system may very well serve as a barrier to Humberto dumping a lot of rain inland, which won't prevent some much needed water reaching the southern states, however it might prevent the middle of the continent from being deluged again. It won't stop Texas from more flooding and people in chronically wet areas this season need relief from FEMA while moving away from those newly forming lagoons and swamps. Seriously.
