A line of Pacific disturbances that pose no land threat
There continues to be no new tropical cyclones active in either the Atlantic or Eastern Pacific basins. However, there are three areas of disturbed weather currently being monitored for development in the Eastern Pacific and one in the Central Pacific. The easternmost disturbance, which has not yet formed, is expected to develop into a low pressure system by early next week. The UKMET and ECMWF models both develop this system into a tropical depression by late Wednesday as it moves…
Invest 90E running out of time to develop
Invest 90E over the Eastern Pacific has struggled to develop persistent deep convection near its elongated center of circulation, and chances of it developing into a tropical cyclone are diminishing. The National Hurricane Center (NHC) gave it a 50 percent chance of development, both within 48 hours and five days in a Special Tropical Weather Outlook issued at 10:25 AM PDT (1:25 PM EDT). This is down from the 70 percent chance NHC gave 90E early Wednesday morning. Because 90E…
Invest 90E becoming better organized over the Eastern Pacific
Invest 90E over the Eastern Pacific has become a little better organized today as it moves west-northwestward through the tropical Pacific. The National Hurricane Center (NHC) gives 90E a 50 percent chance of development, both within 48 hours and five days. Scatterometer data from Tuesday afternoon indicates that the circulation has become much better defined, and an increase in convective organization will likely result in the formation of a tropical depression on Wednesday. 90E is no threat to land. As…
Invest 90E in Eastern Pacific may develop over the next few days
The first “Invest” of the year for the Eastern Pacific – 90E – was designated Monday afternoon. 90E has a medium chance of tropical cyclone development within the next five days, but conditions are expected to become less conducive for development by late week and into the weekend. 90E is no threat to any land areas. An Invest – short for area of investigation – is an area of disturbed weather being monitored for possible tropical or subtropical development. Invests are…
