  1. A disturbance that moved into the Central Pacific from the East Pacific last night has become the second tropical depression to form in the Central Pacific in 2014. 02C has winds of 30kts and consists of a tight LLC with slightly displaced convection and a prominant banding feature wrapping in from the north. 02C is forecast to strengthen into a hurricane by CPHC. Waters are definitely warm enough, but shear values look high to the depression's northwest, which is where 02C is headed. 02C is located just west of 140W and a little north of 10N in the image, which shows the strong shear northwest of the depression: Unless this eases, I find it hard to believe 02C will become a hurricane. CPHC obviously expect that shear to ease, and they are of course the experts! Track wise, 02C is expected to head westwards on the south side of a ridge to the north. An approaching trough is expected to shunt the ridge eastwards in the coming days, creating a weakness and sending 02C to the northwest. Now this is quite significant. If CPHC's forecast verifies, 02C will impact Hawaii as a hurricane. It would be the second strike of the year (the first was Iselle). A lot could change of course, but it is interesting to note.
  2. Invest 97E, located several hundred miles southwest of the southern tip of Baja California, has become Tropical Depression 10E, with winds of 30kts. The system has had a well defined circulation for a couple days now, but moderate shear has prevented convection from persisting. Convection has built closer to the LLCC now, prompting the upgrade to tropical depression. 10E is still under moderate shear, and this will slow the intensifcation of the depression, but isn't expected to stop it all together. In a couple days, shear is expected to ease on the westwards track along the south side of a strong ridge to the north. This should allow at least some steadier intensification at this time. NHC forecast 10E to become a hurricane as it moves toward the Central Pacific.
  3. Tropical Storm Genevieve has formed in the far west of the basin, a long way out to sea. Winds are at 40kts. Genevieve has probably peaked, as shear is increasing over the storm, already displacing convection from the LLCC. Even stronger shear lies on Genevieve's generally westwards path, which will cause Genevieve to weaken soon, as it moves into the Central Pacific.
  4. The Eastern Pacific continues to produce storms with ernest with the formation of Tropical Storm Iselle this evening, located at 12.7N, 122.3E, about 1100 miles southwest of the southern tip of Baja California. Winds are at 35kts. Convection is wrapping nicely around the LLCC of Iselle, with good banding features in the southern and western quadrants. Shear is low on the west-northwest then westward track, and waters warm. Therefore, Iselle is forecast to become a hurricane. Just when this may occur is open to question. NHC mention a signifcant chance of rapid intensification over the next 24hrs, which would not be surprising given the rapidly improving structure and favourable environment. By day 5, Iselle will be nearing the Central Pacific basin, where it's likely to enter as a weakening storm.
  5. A disturbance that formed in the Eastern Pacific basin a few days ago has moved into the Central Pacific basin and become the first tropical depression to form in the basin this year. 01C has a decent amount of convection obscuring the LLCC, with some formative banding. 01C appears to be in a pretty favourable environment characterised by low shear and warm sea temperatures. A typical west-northwesterly track is expected, which does mean that 01C will be moving towards Hawaii, so it does need watching. Central Pacific Hurricane Center (CPHC) will be issuing their first advisory soon, it'll be interesting to see how much strengthening they forecast. 01C's structure and the favourable envionment does suggest that 01C should intensify, at least in the short term. Shear is quite high to the system's northwest, which could cause weakening in the longer term.
  6. The first named storm since Tropical Storm Omeka in 2010 has developed in the Central Pacific, about 1,250 miles southwest of Kauai. Intensity is 35kts. Pewa has deep convection covering the LLCC, which has remained persistant through the day. Pewa is in an area of low shear and warm sea temperatures, and excellent outflow. This suggests that Pewa should intensify over the next few days as it heads west-northwestwards. I would not be surprised to see Pewa become a hurricane at some point in the next few days. In a few days time, as Pewa moves into the West Pacific basin, it should begin to weaken as shear is expected to rise. Even though Pewa is forecast to cross over into the West Pacific basin, it will retain it's name. Track map showing Pewa not far from the international dateline and the West Pacific basin:
  7. A third tropical cyclone in the space of 3 days has formed in the Central Pacific. This is quite something, given that the last system before these three tropical cyclones to form in this basin was Omeka in 2010. Tropical Depression 03C is located about 1000 miles west-southwest of Hawaii and is moving westwards. 03C has formed in an environment that is not particularly conducive, as waters are warm but shear is moderate to high. The depression however, has managed to maintain a persistant area of convection over the LLCC in the face of the shear. Shear is not expected to ease, so 03C is not forecast to strengthen, and instead is forecast to dissipate in about 36hrs time, near the International Dateline.
  8. Tropical Storm Unala has formed in the far west of the Central Pacific, from Invest 90C. I actually suspect this was a tropical storm yesterday, if not a day or so before, and it seems like CPHC are admitting they were late upgrading it based on some of the words of their first advisory. Unala has a small area of deep convection near the LLCC, and an intensity of 35kts. Unala is not in a very favourable environment, as shear is moderate to strong. This is in part due to Tropical Storm Pewa to it's west. Therefore, it is likely Unala is at it's peak and will begin to weaken very soon. In fact, CPHC have just issued a special advisory indicating Unala dissipating in the next 24hrs, as even stronger shear awaits it as it approaches the international dateline. It should however, make it into the West Pacific before dissipation.
