Weather Analysis and Forecasting / Numerical Weather Prediction Conference Student Travel Grant Awards Student presentations selected as part of the 34WAF/30NWP conferences have the option of being judged, with a $50 award going to the top 3 oral and poster presentations in each conference (12 awards total). Also, once abstracts have been submitted, the WAF/NWP committee will offer three $375 travel grants to students whose abstracts have been accepted. Students who wish to be considered for a travel grant must send the following documents to the program chairs (austin.coleman@noaa.gov, john.lind@noaa.gov, jbravo2@stevens.edu, and tomer@windbornesystems.com) no later than Friday, April 3rd, 2026: Statement of why they wish to attend the WAF/NWP conferences - Statement of commitment to attend if they receive the travel grant - Letter of support from their advisor - Ensure that you have submitted an abstract to the WAF or NWP conferences before the abstract submission deadline

Hi everyone! With the abstract submission deadlines for the 2026 AMS Madison Joint Summit coming up, wanted to advertise these student award and travel opportunities available via the AMS WAF/NWP conferences. Feel free to spread the word to any interested students!

UW has a new climate related Postdoc fellowship, application due April 15! Please reach out if you are interested in working with me!

It’s completely gut wrenching. I am so sorry to the many of you that work at NCAR. You do not deserve this.

These people are nuts. NCAR developed the GPS dropsonde, which revolutionized the understanding of TC structure, improved forecasts, and validated remote sensing platforms, as documented in over 400 peer-reviewed publications in the last 25 years. And that’s just one of NCAR’s countless advances.

It’s like being stabbed right in the gut. NCAR is the heart of my field. I can’t. I just can’t.

You VERY rarely ever see a satellite presentation like this anywhere in the world. And you certainly don't expect to see it this close to a mountainous island.
As of 5am EDT on Tuesday, #Melissa is the 8th strongest Atlantic hurricane on record by central pressure (901 mb).

A warning is typically issued36 hours before the anticipated first occurrence oftropical-storm-force winds, conditions that make outsidepreparations difficult or dangerous. Preparations to protect lifeand property should be complete. A Hurricane Watch means that hurricane conditions are possiblewithin the watch area. A Tropical Storm Warning means that tropical storm conditions areexpected somewhere within the warning area within 36 hours. Interests elsewhere in Haiti, the Dominican Republic, Cuba, thesoutheastern and central Bahamas, and the Turks and Caicos Islands,and Bermuda should monitor the progress of Melissa. Additionalwatches and warnings could be required later tonight or tomorrow. For storm information specific to your area, please monitorproducts issued by your national meteorological service. DISCUSSION AND OUTLOOK----------------------At 500 PM EDT (2100 UTC), the eye of Hurricane Melissa was located by Air Force Reserve reconnaissance aircraft near latitude 16.4 North, longitude 77.2 West. Melissa is moving toward the west near 5 mph (7 km/h). A slow westward motion is expected tonight, followed by a turn to the north and northeast on Monday and Tuesday. On the forecast track, the core of Melissa is expected to move near or over Jamaica on Tuesday, across southeastern Cuba Tuesday night, and across the southeastern Bahamas on Wednesday. Maximum sustained winds have increased to near 145 mph (230 km/h) with higher gusts. Melissa is a category 4 hurricane on the Saffir-Simpson Hurricane Wind Scale. Additional intensification is forecast over the next day or so, followed by fluctuations in intensity. Melissa is expected to be a powerful major hurricane when making landfall in Jamaica Monday night or Tuesday morning and southeastern Cuba late Tuesday. Hurricane-force winds extend outward up to 30 miles (45 km) from thecenter and tropical-storm-force winds extend outward up to 205 miles(335 km). The minimum central pressure estimated by aircraft dropsonde data is 941 mb (27.79 inches). HAZARDS AFFECTING LAND----------------------Key messages for Melissa can be found in the Tropical CycloneDiscussion under AWIPS header MIATCDAT3 and WMO header WTNT43 KNHC. WIND: Tropical storm conditions are likely occuring in Jamaica, withhurricane conditions expected to begin by Monday. Tropical stormconditions are expected to begin in Eastern Cuba by Tuesdayafternoon, with Hurricane conditions expected to begin in thehurricane warning area by Tuesday evening. Tropical storm conditionsare ongoing in the warning area in Haiti. The potential for hurricane conditions in the watch area in Haiti have diminished fortoday, but there is still a possibility of hurricane conditionsoccurring there on Tuesday. RAINFALL: Melissa is expected to bring rainfall of 15 to 30 inchesto portions of Jamaica and additional rainfall of 8 to 16 inches forsouthern Hispaniola through Wednesday, with local storm total maximaof 40 inches possible. Catastrophic flash flooding and numerouslandslides are likely. For eastern Cuba, storm total rainfall of 10 to 15 inches, withlocal amounts to 20 inches, is expected by Monday into Wednesdayresulting in life-threatening flash flooding and numerouslandslides. Over the Southeast Bahamas, total rainfall of 4 to 8 inches isexpected Tuesday into Wednesday resulting in areas of flashflooding. For a complete depiction of forecast rainfall associated withMelissa, please see the National Weather Service Storm TotalRainfall Graphic, available athurricanes.gov/graphics_at3.shtml?rainqpf STORM SURGE: Life-threatening storm surge is likely along the southcoast of Jamaica late Monday through Tuesday morning. Peak stormsurge heights could reach 9 to 13 feet above ground level, near andto the east of where the center of Melissa makes landfall. Thisstorm surge will be accompanied by large and destructive waves. There is a potential for significant storm surge along the southeastcoast of Cuba late Tuesday or Wednesday. Peak storm surge heightscould reach 6 to 9 feet above normal tide levels, near and to theeast of where the center of Melissa makes landfall. This storm surgewill be accompanied by large and destructive waves. SURF: Swells generated by Melissa are expected to affect portions ofHispaniola, Jamaica, eastern Cuba, and the Cayman Islands during thenext several days, and In the Bahamas and Bermuda later this week.These swells are likely to cause life-threatening surf and ripcurrent conditions. Please consult products from your local weatheroffice. NEXT ADVISORY-------------Next intermediate advisory at 800 PM EDT.Next complete advisory at 1100 PM EDT. $$Forecaster Papin

A lot of comments on Mars rovers or Moon landings, but it's important to remember that the planet NASA studies most is Earth. This is less about cutting flashy things like moonwalks and more about keeping communities in the dark on climate, weather, agriculture, pollution, natural hazards, and more.

Layoff notices at JPL are going out today.

About 11% of the Lab, or 550 people, are being let go.

I'm thinking of my friends and colleagues there, some of whom will still be employed after today and some of whom won't.

I'm sorry you're having to deal with this.
