The NHC has maintained a HIGH (90%) probability of cyclone formation with PTC TWO, and a MEDIUM (40%) probability with INVEST 95L in the GOMEX, and increased the probability of the tropical wave near 45.0W to 30% during the next 5 days.
NHC GTWO (LINKED)
I am going to begin closer to home this evening with INVEST 95L. As of the 2:00 p. m. ATCF BTK report, the following was available on INVEST 95L in the NW GOMEX:
2:00 PM EDT Wed Jun 29
Location: 25.8°N 95.4°W
Moving: WSW at 5 mph
Min pressure: 1014 mb / 29.94 in
Max sustained: 35 mph
The initial motion was reported as WSW as this drifts slowly tonight and into the morning, and should begin to move more toward the WNW to NW shortly thereafter. Based on forecast steering and model guidance, this disturbance should move over the Texas coast in about 24 hours.
Max. sustained winds were reported at 35 mph. Analysis of current wind shear indicates shear has relaxed from the 25 kts last night, to 15 – 20 this evening. This is allowing for the convection to be somewhat closer to the low level circulation. Based on analysis of the wind field from the MTCSWA site, this doesn’t have a completely closed off center. Current Satellite loop imagery still indicates a disorganized system with limited convective activity. Visible satellite loop imagery still indicates the system is taking in some drier air by the presence of arc clouds, seen rushing out from the center and moving southwestward.
WEATHERNERDS GOES 16 GOMEX SATELLITE IR AND VIS LOOP IMAGERY
Based on my analysis of the wind shear forecast and SHIPS diagnostics, the shear pattern is forecast to improve somewhat, with shear values forecast to be on a favorable level. Analysis this evening indicates surface moisture and relative humidity to be favorable up to 700 mb, with indications of a drier mid level. This will be a hindering factor for development. However these GOMEX systems have been known to flareup just prior to crossing the coast. I am not expecting too much out of this, given the lack of organization, and forecast presence of drier mid level air. However, given the lowering of shear and the very warm Gulf waters, the probability of this becoming a depression as it crosses the coast does exist. The majority of the intensity guidance indicates a depression, with only 4 models indicating a weak tropical storm. I don’t see a TS. right now, given the short time it will be over water.
Regardless of development, heavy rain will be possible along portions of the Texas coast for the next few days.

POTENTIAL TROPICAL CYCLONE TWO
As of the 8:00 p. m. NHC intermediate advisory, the following was available on PTC TWO:
8:00 PM AST Wed Jun 29
Location: 11.9°N 69.7°W
Moving: W at 21 mph
Min pressure: 1009 mb / 29.80 in
Max sustained: 40 mph
Based on careful analysis of satellite loop imagery, the system hasn’t shown any real changes in organization this evening, and still appears somewhat elongated. The system continues to move toward the west, at a forward speed of 21 mph. Based on analysis of the current steering layer, this motion is due to the strong flow on the southern edge of the subtropical ridge. Based on this, and analysis of forecast steering layers maps, I expect this motion to continue during the next 24 hours, before the forecast steering pattern allows for a slight shift south in track, but continuing due west. This should allow for the system to exit into the EPAC in a few days. Based on this, I concur with the NHC forecast track.
WEATHERNERDS GOES 16 SATELLITE LOOP IMAGERY
Based on information in the NHC discussion, PTC TWO is still trying to close off a complete circulation. Based on how close the center is to the South America coast, this may not occur until the center moves away from the coast, albeit the NHC indicates this could become a cyclone at any time.
Based on my analysis of current and forecast wind shear maps, the PTC is not under any shear to speak of, and the forecast calls for shear to remain low and in a favorable pattern. Current intensity guidance now indicates only a tropical storm, vice hurricane prior to landfall. This could very well be, given the proximity to land, and the fast forward speed. Once this gets to open water and if it slows down, some steady strengthening may occur, prior to landfall. We’ll have to see if there are any changes to the forecast pattern during the next 24 – 36 hours, that may indicate a bump to minimal CAT 1. For the time being, I concur with the NHC intensity forecast, based on my analysis.

KEY MESSAGES FROM THE NHC
WIND SPEED PROBABILITIES
FROM THE NHC ADVISORY:
WATCHES AND WARNINGS -------------------- CHANGES WITH THIS ADVISORY: The Meteorological Service of the Netherlands has discontinued the Tropical Storm Warning for Bonaire. SUMMARY OF WATCHES AND WARNINGS IN EFFECT: A Hurricane Watch is in effect for... * Nicaragua/Costa Rica border to Laguna de Perlas Nicaragua A Tropical Storm Warning is in effect for... * Curacao * Aruba * Coast of Venezuela from the Peninsula de Paraguana westward to the Colombia/Venezuela border including the Gulf of Venezuela * Coast of Colombia from the Colombia/Venezuela border westward to Santa Marta A Tropical Storm Watch is in effect for... * Limon Costa Rica northward to the Nicaragua/Costa Rica border * North of Laguna de Perlas to Sandy Bay Sirpi Nicaragua A Hurricane Watch means that hurricane conditions are possible within the watch area. A watch is typically issued 48 hours before the anticipated first occurrence of tropical-storm-force winds, conditions that make outside preparations difficult or dangerous. A Tropical Storm Warning means that tropical storm conditions are expected somewhere within the warning area, in this case within the next 24 hours. A Tropical Storm Watch means that tropical storm conditions are possible within the watch area, generally within 48 hours. Interests elsewhere along the northern coast of Venezuela and the northern coast of Colombia should monitor the progress of this system. Interests elsewhere along the Caribbean coasts of Nicaragua and Costa Rica should also monitor the progress of this system. For storm information specific to your area, please monitor products issued by your national meteorological service.
HAZARDS AFFECTING LAND ---------------------- Key messages for Potential Tropical Cyclone Two can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDAT2 and WMO header WTNT42 KNHC. RAINFALL: The Potential Tropical Cyclone is expected to produce heavy rain across the ABC Islands to portions of northern Venezuela and northeast Colombia through Thursday morning, then across Nicaragua and Costa Rica by Friday. The following storm total rainfall amounts are expected: North-Central Venezuela: 4 to 6 inches. Aruba, Curacao and Bonaire to northwestern Venezuela and northern Colombia: 3 to 5 inches. Nicaragua and Costa Rica: 3 to 7 inches, with isolated higher totals around 10 inches. WIND: Tropical storm conditions are expected over the ABC Islands in the warning area for the next few hours. Tropical storm conditions are expected in the warning area along the northwestern coast of Venezuela and along the coast of northeastern Colombia tonight and early Thursday. Hurricane conditions are possible within the Hurricane Watch area in Nicaragua late Friday, and tropical storm conditions are possible within the watch areas in Nicaragua and Costa Rica by Friday afternoon or evening.
Residents within the HURRICANE WATCH area should be making preparations at this time.
I will continue to monitor both INVEST 95L and PTC TWO over the next 36 – 48 hours for any significant changes.
Elsewhere, I do not anticipate Tropical Storm Formation during the next 5 days.

Have a blessed evening!
