09AM MDT 05/30/07 Alvin (magenta arrow) has been downgraded to a Tropical Depression as it moves west. The second tropical cyclone (red arrow) has been upgraded to Tropical Storm Barbara. The storm is stationary but is expected to continue to strengthen and turn to the NW along the southern coast of Mexico. A thermal Low (orange arrow) over the mainland is expected to affect the storm. Some broken clouds and marine layer (yellow arrow) may keep skies in the central and northern parts of the peninsula cloudy early, but should burn off later in the day. The Pacific High off our map to the west (blue arrow) continues to keep the rest of Baja clear and dry.

08AM MST 05/29/07 Tropical Storm Alvin (red arrow) became the first named storm of the 2007 Hurricane Season when it was upgraded last night by the NHC. Alvin is expected to remain a Tropical Storm for the next few days as it moves harmlessly west into the Pacific. Baja will have sunny skies, after morning Pacific marine layer burns off. La Paz even has a thick layer this morning. Temperatures in the afternoon should be seasonal. Our weather will be dominated by the Pacific High (blue arrow) off our map to the west. Another system (magenta arrow) shows signs of development and may become a tropical depression later today.

08AM MST 05/28/07 Tropical Depression 1E (red arrow) has formed some 715 miles SSW of Cabo San Lucas and is moving west. The system is forecast to become our first named storm of the season as it builds to become Tropical Storm Alvin before Tuesday morning. The system is unlikely to affect Baja weather. Our Baja skies should be clear and hot after a marine layer burns off the Pacific coast north of El Rosario. The Pacific High off our map to the west (blue arrow) will keep Baja dry. A thermal Low (yellow arrow) is drawing and tropical moisture over the mainland. Two troughs are moving the through the Caribbean (orange arrows) Winds in the Sea should be under 10kts during the day and to 15kts after sunset from the west.

09AM MST 05/23/07 In Baja Sur SW winds are bringing a pacific marine layer across the peninsula, keeping mornings temps in the low 60°F's. Corumuel Winds continue to blow along the southern Sea of Cortez to 15kts after sunset. There will e some heavy clouds in the northern most sections of Baja California, but about 2/3's of the peninsula will enjoy sunshine. Temperatures will be slightly below seasonal. This good weather is a result of the Pacific High (blue arrow) The Pineapple Express or tropical moisture as it it's called at this time of year (yellow arrow) is being drawn into central Mexico and a thermal Low (magenta arrow) a through (red arrow) extends northward into Texas where a line of severe thunderstorms is moving east. Another trough (orange arrow) is moving NW through the Caribbean.

09AM MST 05/22/07 Corumuel Winds continue to blow along the southern Sea of Cortez to 20kts after sunset from the SW to WSW. It will be clear, sunny and dry over al of the Baja peninsula today as our weather continues to be dominated by the Pacific High (blue arrow) off our map to the west. just traces of the Pineapple Express moisture (yellow arrow) are able to survive in the dry air environment. There is a long string of thunderstorms (magenta arrow) west of our Hurricane basin and unlike to generate tropical cyclone activity. A trough is moving SW in the Caribbean (orange arrow) but will find very dry air on the Pacific side when it arrives later this week. A line of severe weather (red arrow) is pushing east through eastern Texas.

09AM MST 05/21/07 A Low (orange arrow) moving into So Cal is causing a gale in the So Cal Bight in opposition to the Pacific High (blue arrow) off our map to the west. A tiny puff is all that is left of the Pineapple Express (yellow arrow) leaving all of Baja with bright sunny skies. There is a thermal Low over the mainland (green arrow) Baja Sur can expect strong Corumuel Winds from the WSW in the evening through the week. There is a Low (red arrow) that may cross into the Pacific Basin in the next 36hrs which may provide some of the ingredients for our first Pacific tropical cyclone over the next few days in the ITCZ..

09AM MST 05/18/07 Just our regular early summer weather throughout Baja today. The north and south of the peninsula wlll be clear while a faint trace of the Pineapple Express (yellow arrow) moves across the central portions. Winds throughout the Sea are expected to be light and variable during the day and 15kts from the WSW in the southern Sea and to 20kts in the northern Sea after sunset. The Pacific High off our map to the west (blue arrow) will keep moisture low and skies clear. There is some moderate thunderstorm activity in the ITCZ (orange arrow) and a Low (magenta arrow) in the Caribbean that may travel across the Isthmus with a trough and present the first possibility for tropical cyclone formation in the Pacific late in the weekend. This early in the season it is improbable that it would present a threat to Baja.

08AM MST 05/15/07 May 15th marks the start of the Eastern Pacific Hurricane Season and we have expanded the coverage area of our map to include the tropical areas. The Pacific High off our map (blue arrow) continues to dominate Baja weather and in conjunction with a very shallow thermal Low (green arrow) over the mainland to provide light winds from the WSW for most of Baja. Sunny skies will also rule from Baja California to Baja Sur. The ITCZ (orange arrow) will creep north over the next several months until creating a credible threat to Baja weather around August 15th. There is significant thunderstorm activity along the ITCZ well west of the hurricane birthing grounds. The 26°C thermo cline (red arrow & line) is significant in cyclonic development.

11AM MST 05/02/07 Winds will let up through much of Baja during the day today, but strong Corumuel Winds are expected after sunset. This is normal at this time of year because of the temperature difference between the pacific, the land and the Sea of Cortez. The Pacific High (blue arrow) off our map to the west is creeping closer to the California Coast and we may see stronger winds later in the week. A thermal Low (orange arrow) is over mainland Mexico in opposition to the High. Another late season cod front north of our map (green arrow) will sweep through California in the next few days and will bring clouds and cooler temps to Baja California. In Baja Sur temps will continue to warm as the last traces of the Pineapple Express (yellow arrow) are swept SE. A early season trough is moving west along the ITCZ (magenta arrow)
