First low pressure system of the season

The Eastern Pacific hurricane season starts on the 15th, only four days away. This Invest 90 is a few days early but probably will bring nothing but clouds and a bit of rain. This season is expected to be busier than the past two which were below normal. Most activity is scheduled for late in the season due to El Nino effects. West coast of Mexico

First "Invest" of the season

The Weather Underground link below is to the first tropical weather pattern starting to develop in the E. Pacific. CNA calls for more gusty winds this afternoon - yesterday was the coolest weather we've seen in weeks and today should be about the same. Yesterday's high temp was 82.4F/28C - low was 75.5F/24C - humidity ranged from 64 to 74%. The constant breeze is keeping the ocean temperature down to just below comfortable

Invest 90 is it's name and we'll have many Invests over the year, 91's 92's, etc. I always wondered what the numbering denotes or even the term Invest . This is the best I could come up with from a weather related message board.

These "Invests" are usually first listed on the Navy's weather page.... and are numbered 90-99 and have a letter attached, identifying the basin in which are they are located. L- Atlantic. E- East Pacific. W- West Pacific., etc...etc...etc... Once an Invest is declared, the NHC starts running model data on that particular system."
