After a 3 week lull the third tropical depression of the East Pacific season has formed in the eastern half of the basin, well south of the Mexican coast. Intensity is 30kts. 03E is a large tropical depression with sprawling bands and a small area of deep convection over the LLCC. Over the next few days, 03E is forecast to move on a typical west-northwest track on the southern side of ridging over Mexico. This gives the depression about 4 days over warm water to strengthen. Shear is expected to be low to moderate, so 03E is forecast to become a hurricane before reaching cooler waters.

Already larger than Texas apparently.

Overnight, 03E has undergone some structural changes. The sprawling bands have morphed into a large central dense overcast feature, and the LLCC is located on the northern edge of this mass of intense convection, due to moderate shear. Intensity has increased to 35kts, and 03E is now Tropical Storm Cosme.

 

Cosme has jogged westwards whilst undergoing these changes. However, the west-northwest to northwest track will resume later today. Cosme should continue to strengthen, especially as the shear begins to ease later today and the sea temps remain warm along track for the next few days. Cosme's large size argues against rapid strengthening, but Cosme should still have time to become a minimal hurricane before weakening begins.

Tropical Storm Cosme has formed in the Pacific southwest of Mexico and is expected to stay away from the country's coast. The storm's maximum sustained winds early Monday are near 40 mph (65 kph). The U.S. National Hurricane Center in Miami says some strengthening is expected and the storm could become a hurricane by Tuesday night or Wednesday.
 
Cosme is centered about 435 miles (695 kilometers) south of Manzanillo, Mexico, and is moving northwest near 10 mph (17 kph).

Cosme has continued to strengthen. Intensity is now 45kts. The storm remains large in size, but the central dense overcast appears to be deepening and the LLCC is fully tucked beneath the deepest convection.

Cosme looking pretty impressive on satellite, definitely a maturing tropical storm. And certainly a very large one at that. Despite being several hundred miles away from the Mexico coast, Cosme's bands are still lashing the coast with heavy rains.

Cosme has intensified further overnight, and winds are now at 55kts. The storm has developed a central dense overcast, flanked by tightly wrapped banding. The storm will likely become a hurricane in the next 12 hours, and is forecast to peak at 75kts in 24-36hrs time before the west-northwest track brings Cosme into cooler water and increasing shear.

MIAMI: Tropical Storm Cosme is strengthening in Pacific waters southwest of the Mexican mainland and forecasters say it's expected to become a hurricane within a day.
 
The storm's maximum sustained winds have risen to 65 mph (105 kph) as of late on Monday. The US National Hurricane Center in Miami says more strengthening is expected in the coming 48 hours with Cosme expected to become a hurricane sometime on Tuesday. Cosme is centered about 320 miles (515 kilometers) southwest of Manzanillo, Mexico, and is moving northwest at 14 mph (22 kph).
 
No coastal watches or warnings are in effect. The hurricane center says ocean swells generated by the storm will begin affecting a swath of the Pacific coast from Manzanillo to Cabo Corrientes overnight with life-threatening surf and rip currents possible.

Cosme has strengthened some more and is now a 65kt, cat 1 hurricane. Cosme maintains a central dense overcast with glimpses of an eye from time to time. Cosme has about another 12 hours to strengthen, before cooler waters induce a weakening trend.

It's a bit of an ugly hurricane given all the banding but a good system.

Cosme is likely peaking. Winds are up to 75kts this morning. Already, convection is weakening long the western half of the hurricane, indicative of movement into cooler waters and a more stable airmass. Cosme retains some deep convection over the centre, but it is slowly shrinking with time. Weakening should commence this afternoon as Cosme heads west-northwestwards. As Cosme weakens, it should turn westwards as the increasingly shallow cyclone gets steered in the low level easterly flow.

Hurricane Cosme has strengthened to its likely peak intensity in the Pacific Ocean well off the coast of Mexico. The hurricane had top sustained winds of 85 mph (137 kph) late Tuesday. Forecasters say the storm will gradually weaken Wednesday and Thursday.
 
The U.S. National Hurricane Center in Miami says Cosme is centered about 410 miles (660 kilometers) south-southwest of Cabo San Lucas, Mexico, and is moving west-northwest at 14 mph (28 kph). The center says the storm is generating large swells that are affecting parts of Mexico's Pacific coast and its Southern Baja California Peninsula. The swells are likely to cause dangerous surf and rip current conditions.
 
No coastal watches or warnings are in effect.

Cool waters have taken their toll on Cosme, and the system has been downgraded to a tropical storm with winds of 50kts. The eyewall has gone and the convectiion is waning. Waters of around 21-23C are expected to weaken Cosme further, and it shouldn't be long before the cyclone degnerates into a remnant low.

Have to say it actually looks prettier now than when it was a hurricane however there looks to be some relative shear perhaps caused by the quick speed as the mid level and surface circulations don't look stacked vertically to me.

Tropical Storm Cosme weakening in the Pacific
 
Tropical Storm Cosme (KAHS'-may) continues to weaken in the cold waters of the Pacific Ocean well off the coast of Mexico.

Cosme is on the verge of being declared a remnant low. There has been no convection for at least 12 hours now, and the LLCC is gradually spinning down. Intensity has fallen to 35kts. Unless a flare up of convection occurs (unlikely due to the cold sea temps), then the next NHC advisory will be the last.

Incredible to see on satellite but yeah, the mid level circulation is pretty much non-existent and there's no vertical stacking to speak of to ignite convection.

Cosme was declared a remnant low last night. Regeneration is not expected.
