Even though convection across this region is less frequent than in many other parts of the country significant thunderstorm events and occasional severe weather does occur. It has been found that a further challenge in convective forecasting across southern California is due to the variety of sub-regions that exist including coastal plains, inland valleys, mountains and deserts, each of which is associated with different weather conditions and sometimes drastically different convective parameters. In this paper four recent thunderstorm case studies were conducted, with each one representative of a different category of seasonal and synoptic patterns that are known to affect southern California. In addition to supporting points made in prior literature there were numerous new and unique findings that were discovered during the scope of this research and these are discussed as they are investigated in their respective case study as applicable. -

It is of interest to note, historically, that much of the f'unda- mntal Infomaation on atolls of the Pacific was gathered by the U. S. Navy's South Pacific Exploring Ekpedition, over one hundred years ago, under the cormnand of Captain Charles kfillres. The continuing nature of such scientific interest by the Navy is shotm by the support for the Pacific Science Board ' s research programs during the past fourteen years. me preparation and issuance of the Atoll Research Bulletin is assisted by fbds from Contract N70nr-2300(12).

Local Hazard Mitigation Plan
City of Waveland Local Hazard Mitigation Plan March 2013 EXECUTIVE SUMMARY The purpose of hazard mitigation is to reduce or eliminate long-term risk to people and property from hazards. The City of Waveland developed this Local Hazard Mitigation Plan (LHMP) update to make the City and its residents less vulnerable to future hazard events. This plan was prepared pursuant to the requirements of the Disaster Mitigation Act of 2000 so that Waveland would be eligible for the Federal Emergency Management Agency’s (FEMA) Pre-Disaster Mitigation and Hazard Mitigation Grant programs. The City followed a planning process prescribed by FEMA, which began with the formation of a hazard mitigation planning committee (HMPC) comprised of key City representatives, and other regional stakeholders. The HMPC conducted a risk assessment that identified and profiled hazards that pose a risk to the City, assessed the City’s vulnerability to these hazards, and examined the capabilities in place to mitigate them. The City is vulnerable to several hazards that are identified, profiled, and analyzed in this plan. Floods, hurricanes, and sea level rise are among the hazards that can have a significant impact on the City. Based on the risk assessment, the HMPC identified goals and objectives for reducing the City’s vulnerability to hazards. The goals and objectives of this multi-hazard mitigation plan are: Goal 1 Minimize risk and vulnerability of the community to hazards and reduce damages and protect lives, properties, and public health and safety in the City of Waveland Prevent and reduce flood damage and related losses Minimize impact to both existing and future development Minimize economic and resource impact Goal 2 Provide protection for critical facilities, infrastructure, and services from hazard impacts. -

The Contribution of Eastern North Pacific Tropical Cyclones to The
AUGUST 2009 C O R B O S I E R O E T A L . 2415 The Contribution of Eastern North Pacific Tropical Cyclones to the Rainfall Climatology of the Southwest United States KRISTEN L. CORBOSIERO Department of Atmospheric and Oceanic Sciences, University of California, Los Angeles, Los Angeles, California MICHAEL J. DICKINSON Weather Predict Consulting, Inc., Narragansett, Rhode Island LANCE F. BOSART Department of Earth and Atmospheric Sciences, University at Albany, State University of New York, Albany, New York (Manuscript received 26 August 2008, in final form 6 March 2009) ABSTRACT Forty-six years of summer rainfall and tropical cyclone data are used to explore the role that eastern North Pacific tropical cyclones (TCs) play in the rainfall climatology of the summer monsoon over the southwestern United States. Thirty-five TCs and their remnants were found to bring significant rainfall to the region, representing less than 10% of the total number of TCs that formed within the basin. The month of September was the most common time for TC rainfall to occur in the monsoon region as midlatitude troughs become more likely to penetrate far enough south to interact with the TCs and steer them toward the north and east. On average, the contribution of TCs to the warm-season precipitation increased from east to west, accounting for less than 5% of the rainfall in New Mexico and increasing to more than 20% in southern California and northern Baja California, with individual storms accounting for as much as 95% of the summer rainfall. The distribution of rainfall for TC events over the southwest United States reveals three main categories: 1) a direct northward track from the eastern Pacific into southern California and Nevada, 2) a distinct swath northeastward from southwestern Arizona through northwestern New Mexico and into southwestern Col- orado, and 3) a broad area of precipitation over the southwest United States with embedded maxima tied to terrain features.
