Hurricane Andres (above) in the eastern tropical Pacific was on 2 June 2015 joined by Tropical Storm Blanca (below). Blanca was forecast to become a Hurricane later on 2 June as Andres weakens. The circulation of Andres, above, is well-established, with good anti-cyclonic outflow and curved inflow bands. Shear values<\/a> are low. (Graphics come from this site<\/a>). However, Andres has moved over relatively cool Sea Surface Temperatures<\/a> that spell weakening.<\/p>\n

Blanca, in contrast, has a circulation that is not so well-defined. However, the storm is over very warm water<\/a>, and also in a region of relatively low shear<\/a>. Strengthening is forecast.<\/p>\n

The animation of Andres at top shows a ragged appearance as dry air intrudes upon the circulation from the south and west. This dry air is apparent in the MIMIC<\/a> Total Precipitable Water animation below. The circulation of Blanca appears at the end of the animation, embedded within a rich source of tropical moisture.<\/p>\n

Sea-surface temperatures off the Pacific Coast of Mexico have been warmer than normal for much of this year (Map<\/a>, data from here<\/a>). Warmer-than-normal sea-surface temperatures argue for stronger hurricanes, and Andres was a Category 4 storm on 1 June<\/a> with a well-developed eye. Andres is one of only 5 May storms in the eastern Pacific since 1970 to achieve Major Hurricane status (Link<\/a>).<\/p>\n

Aqua overflew Andres shortly before 1800 UTC on 1 June, and the water vapor imagery of the storm at that time is here<\/a>. The True-Color imagery is shown below.<\/p>\n

A storm-centered animation over Andres’ lifecycle is shown below. The storm starts in the moisture-rich ITCZ and ends as an isolated region of moisture surrounded by dryness.<\/p>\n
